I regret to tell you this, but, the whole truth is: Taking out a diesel and installing a 4AFE will require you to change the entire engine room wiring harness (including the fusebox), the proper 4AFE (manual or auto trans ECU), the fuel pump and the fuel filter, the air intake system, and most def the dashboard harness (which also connects to the ECU). What you have here is 2 entirely different worlds, gasoline vs diesel.
I would not recommend you to undertake this job, unless you have a complete "donor" vehicle for the abovementioned parts.

The timing belt is one tooth off. Pull the covers back off, set the engine to TDC and recheck your marks, and make sure that the tension is correct.

SOURCE: Engine iddle speed need adjusting

You cant adjust it. Your car has a tps sensor " throttle position sensor " and a iac idle air control. these are both on the throttle body. is the check engine light on? The best way to check them is on a scanner at places like auto zone they will let you use one for free. and will help you do it. first check the codes if any then look at live data scroll down till you see tps and look at its values rev the motor up and it should change values are 0% to 100% no throttle to full throttle. at idle it should be 18 to 26 or so. if it doesnt change or its at a high number and no gas is being given then its bad. also look at the iac and see if it changes as well. you can also google the resistence values for each and ohm them out. It does sound like a bad tps. try that first , and the tps is easy to change

SOURCE: need to know how to adjust valves, or a print-out

This engine utilizes shims to set proper clearances, you will need a micrometer, valve clearance adjustment tool set for shimmed lifters,small magnetic arm, appropriate shim selecting charts (manufacturer will have this if you can get the nec. measurements).
Measure thickness of shims removed (using micrometer) and use this formula where T=Thickness of old shim; A=Valve clearance measured; N=Thickness of new shim required.
Intake valves:   N = T + (A - 0.02 mm (0.008 in.)) Exh. valves:     N = T + (A - 0.25 mm (0.010 in.))
Then you need to find shims as close as possible to the calculated values.
Valve clearances (cold) are as follows: Intake 0.15 - 0.25 mm (0.006 - 0.010 in.) Exhaust 0.20 - 0.30 mm (0.008 - 0.012 in.)
Note, if you are not familiar with precision measuring using a micrometer, this may be better left to a trained tech. These are high revving little power plants and you don't want a problem at 8K rpm.

Why wont my car stay running after it stars?

what engine???????????????????????????
how many miles on it, ever do the belt service> in the operator guide fo the CAM?
doing a full tuneup BY THE BOOK
is not guessing, its called normal service. so you did that (ALMOST).
but what engine option, and the cam belt , did you do the cam belt service per the book? i bet not.
so can your fast right foot keep it running>? (key word STAY)
the car , is really a TOyota Corolla, made in NUMMI plant in Cal.
the engine used is a TOYOTA.
and is common. 4A names are toyota.
the G engine (GE) has major changes.
that it employed a "slave cam system", the camshafts being geared together and driven off one camshaft's sprocket (both camshafts' sprockets on the G-Engine are rotated by the timing belt)

so i ask you, which engine? FE or GE?
aka; VIN 6 or V5 engines. The vin tells which one you have.
when buying parts they will ask you this. just like me.

on old cars, all, i check compression first.
there are many reasons, AGE and not wanting to run burned head valves into the ground $$$$$$
the service chart lists the belt as 60,000 miles
if not changed in time it will slip, and not run.
and compression drops, or cam stops spinning, is it spinning?

here is the logic
i check for spark first. (it cranks)
i see spark on all 4, ok, that is good.
so i check test fuel, it fails.
i then check compression its 80 not 150
i find the belt slipped. all cars run over the spec range do.
see how far you can get watch Mr. Scotty

wow, i love MR2, sell it to me.... lust..... sorry.......
USA Car?????????
its sucking fuel, can be lots of things
got the FSM yet?, keeping a very old car like this going without the big book is near impossible...... really... why work blind>?
you got the 4A non turbo engine>?

1.6 L 4A-GE DOHC I4 (AW11)

wiki (USA)
As a power plant, Toyota chose to use the naturally aspirated 4A-GE 1,587 cc inline-four engine, a dual overhead-cam, four-valve-per-cylinder motor.[5] This engine was also equipped with DENSO electronic port fuel injection and a variable intake geometry ("T-VIS"), giving the engine a maximum power output of 112 hp

first what engine then what fuel injection.
Study the Denso system first, then trouble shoot.
If I had this, car i'd :
1: make brakes perfect.
2: fix all fuel leaks, every inch checked,!!!! top reason for midengine car fires...
3: compression on all cylinders (WOT) 150PSI or more.
4: full tune up with all fluids. really !
5: i'd then check all the EFI sensors and have the the injectors pro cleaned off car, (sonic cleaned)
6: engine thermosat holding water temp at 180F or more steady!!!
7: back flush every inch of cooling system and sub parts.

after all that id diagnose it.
starting with fuel pressure tests , all 6 of them.

Replacing oil pan in 1990 Toyota Corolla

Vehicles covered: Toyota Corolla, 4A-F, 4A-FE, and 4A-GE Engines

Here's your maintenance manual entry for the complete procedure:


4A-F, 4A-FE and 4A-GE Engines

See Figures 1 through 7

1. Disconnect the negative battery cable.

2. Raise and safely support the vehicle.


Fig. 1: Exploded view of the oil pan assembly-4A-F and 4A-GE engines

3. Drain the engine oil into a suitable container.


Fig. 2: Remove the oil pan drain plug to drain the engine oil from the crankcase

4. Place a jack under the transaxle to support it.

5. Remove the splash shield from under the engine.

6. Raise the jack under the transaxle slightly.

7. Remove the front exhaust pipe between the exhaust manifold and catalytic converter. Some models have an oxygen sensor, disconnect the oxygen sensor wiring.


Fig. 3: Remove the front exhaust pipe for better access during oil pan removal

8. On the 4A-F and 4A-FE engines, remove the center mounting.


Fig. 4: Remove the bolts and nuts retaining the center mounting-4A-F engine

9. Some 4A-FE engines and all 4A-GE engines are equipped with a stiffener plate. Remove the set bolts and pull the stiffener plate from the vehicle.

10. On the 4A-GE engines, unbolt and lower the flywheel housing under cover.

11. If equipped, remove the oil cooler hose and union from the oil pan. Remove the two nuts and nineteen bolts retaining the oil pan.

12. Insert a blade between the pan and cylinder block, cut off the applied sealer and remove the pan.


Fig. 5: Insert a blade and tap lightly to loosen the oil pan free from the block

To install:

Note: Be careful not to drop any oil on the contact surfaces of the pan and block.

13. Using a razor blade and gasket scraper, remove all traces of packing (FIPG) material from the gasket surfaces. Thoroughly clean all main surfaces to remove loose material. Clean both sealing surfaces with non-residue solvent.


Fig. 6: Apply a reasonable amount of sealant (FIPG) to the oil pan surface-except 7A-FE engine

14. Apply new packing (FIPG) 08826-00080 to the oil pan as shown. Avoid applying excessive amounts to the surface. Be especially careful around the oil passages.

Note: Parts must be assembled within 3 mins of application. Otherwise, the sealer (FIPG) must be removed and reapplied.

15. Install the oil pan over the studs on the block with the nineteen bolts and two nuts. Tighten the bolts to 43 inch lbs. (5 Nm). Make sure when you install the oil pan drain plug using a new gasket.


Fig. 7: Tighten the 19 oil pan retaining bolts securely-4A-F, 4A-FE and 4A-GE engines

16. If equipped, install the oil cooler pipe, two new gaskets and union bolt. Tighten the union bolt to 18 ft. lbs. (25 Nm).

17. Install the front exhaust pipe (with new gaskets on either end of the pipe) to the manifold.

18. On the 4A-GE engines, install and secure the flywheel housing under cover if removed.

19. On the 4A-FE engines if removed, attach the stiffener plate. tighten the No. 1 bolt first then the 5 bolts in the sequence shown. Tighten to 17 ft. lbs. (23 Nm).

20. On the 4A-GE engines, attach the stiffener plate with the 3 set bolts and tighten them to 27 ft. lbs. (37 Nm).

21. Attach the center mounting and tighten the member side bolts to 38 ft. lbs. (52 Nm), plate side to 17 ft. lbs. (23 Nm).

22. Lower the jack from the transaxle.

23. Lower the vehicle, and fill the crankcase with the appropriate amount of engine oil. Engine oil crankcase capacity is 3.4 quarts (with oil filter change).
Above -9 degrees Fahrenheit, use 10W-40 motor oil, and above 10 degrees Fahrenheit, use 20W-50 motor oil.

24. Connect the negative battery cable, start the engine and check for leaks. If all is well, raise the vehicle slightly and install the engine splash cover.

25. Recheck the engine oil level, top off if necessary.

Actual timing would depend on what engine is installed in the 1985 Corolla. There are some versions that uses the 4A-GE, 4A-GEC, 4A-C engines. There are even some Asian versions that used the 4K/B engines.

The correct method would be to use timing light, engine analyzer and some other test equipment, However, below is a quick and dirty procedure. Basically, to adjust the distributor timing, you need to:
1. make sure cylinder 1's piston is at firing position/TDC (top dead center);
2. crankshaft pulley's timing mark is between the markings on the engine with numbers on them;
3. unplug the rubber boot of the high tension wire for #1 cylinder;
4. connect to it a spare known good spark plug and allow to touch any metal surface of the engine;
5. slightly loosen the single locking bolt of the distributor stem;
6. turn ignition key to ON but not start;
7. carefully swing the distributor assembly till there is spark in the exposed spark plug;
8. tighten locking bolt.

You may need to readjust the distributor for highest idling RPM with the engine running by simply turning the entire distributor assy.

The timing mark must coincide with the specified advance for whatever engine is used by the Corolla. 8 degrees would be a fair start.

Extreme care when working with engine running; extremely high voltage at the high tension wires, distributor and ignition coil and the fan/belt has been known to catch loose clothing.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
