Try looking near the bottom pulley or around the gearbox housing near to where it bolts to the engine

How do I line up my cas sensor on my ca18det properly? And if it's out by much would that cause my car to splutter when driving?

Crank angle sensor =CAS DTC code 11 .
Cam angle sensor = CAS s work best. for sure.
i think this engine it is both !
there is no distributor it has 4 COPs coil over plug
and 1 ignitor module l , that nissan calls the power transistor pack. or PTU, the CAS on this car is really 2 sensors in one.
1 for cam angle and TDC (its a bit sloppy but back then no OBD2 rule to kill this idea)
they call it the crank sensor but is connect to the cam.

what car, what year, ? what country?

and sputter yes.
why not post exact year and car body mode.
or do like we all do
and log in and read the CAS timing , on your car. or buy the FSM.

here is the lest of cars using this engine.
The 1.8 L CA18DET was the last version of the CA engine to be released. It produces 167 hp (124 kW) and 166 lb·ft (228 Nm). It received a brand new DOHC aluminum head with 16 valves. The turbocharger was also upgraded to a Garrett T25 (.48 A/R) unit for increased flow capacity, and as such, was fitted with an intercooler to help prevent the onset of pre-ignition and/or detonation. Fuel was delivered via Multiport Fuel Injection. Bore is 83 mm (3.3 in), and stroke is 83.6 mm (3.29 in). An electronically controlled fuel injection system was used with 370cc injectors.
It was used in the following vehicles:
we run a 200sx in South America. Custom Turbo. ECU and all.

Our engine CAS sensor, has slots see them?
see it.

This engine has no timing freeze DLC (check-conn)like most engine.
hot normal idle speed, set it to FACTORY spec. 15deg. BTDC
do not guess. the ECU hates that. it assumes it is correct
and if not, will mess up big time. Set it to spec. and LEAVE IT.

if you dont have an FSM or a book showiing how to set timing
ask for one, buy one, or google for it.

if a turbo, and you guess, 4 cracked pistons is your future.
here is the fRee FSM
see page EC22 for spark timing.

down load the zip extract it the PDF is the shop manual.

did you run the ECU diagnostics, yet?, RTM.?
for IS the Check engine lamp glowing running?

toy and nissan have the best FSM , of all.
very BIG on diagnosis, unlike USA cars.
the ECU has switch see that?
and if a crank or cam sensor misfires, it will tell you it did.
I'm sure.
the ECU has 5 modes of diagnosis. a very nice ECU.
page 186

Now the real TOPIC :

Misfire is 50 reasons or just 3, (micro, and macro viewed logically
1: bad engine , low compression on any cylinder or all (timing belt slip is all) 150 PSI is minimum. for me. RTM
2: bad /weak/timed wrong, spark. (cas set wrong) test spark on all cylinders. and set the timing, if found way off the cam belt slipped)
never doing a 60,000 mile tune? duh factor 1?
3: bad fueling. too rich turns spark plugs (new?) black. and misfires.
lean fueling causes, bogging and lost engine power.
flooding can be caused by may things, it is , ask how to find this easy.

misfire causes the engine to shake does it?

ever consider a new cam timing belt, or do you want to risk it snapping or slipping?
all Nissans are interference engine. if the belt slips BAM, kiss off a nice motor.

1987 Nissan 200sx starts but wont stay running, new fuel pump, fuel filter, distributer

96 nissan 200sx started and ran rough for 10 sec then died and wont restart. distributor is turning. no fault codes. has good fuel pressure. spark looked weak so i changed cap and rotor. still wont start....

something to ponder over here as iam not sure what could be the problem here but if its a weak spark then it could be module /coil/crank sensor in that order .These problems will not show up as fault codes i dont think as they are working but not to full efficiency

1987 Nissan 200SX cranks but hard to start

Thats a classic sign of having your engine run too rich. That puffy layer of ash is carbon which means your engine is not burning gas properly or completely which means is misfiring thats why the car is shaking. Try having your oxygen sensors checked and make sure you are using good fuel.

My 1996 nissan 200sx won't start

If the starter fluid worked for a little and the engine died again, it may be some of your filters. Check the air and fuel filters and replace them if they are dirty or haven't been replaced in a long while. This is the most common reason a car won't start.

Another idea is the engine may have been flooded. If you have a fuel injected engine, don't pump the fuel when trying to start it. The fuel pump primes the engine all on it's own. If the engine is already flooded, push the fuel pedal all the way to the floor and hold it there while you try to start the engine. This bypasses the priming and opens the air to blast any unburned fuel out of the cylinders.

Check to make sure you are getting spark with an inline spark tester (at auto parts stores) and if not try replacing (in order) the spark plugs, wires and (depending on your engine) the magneto's or distributor cap. Ask the auto parts store if they can look up if you have a distributor-less ignition or if you have a distributor.

So, first the filters (air and any fuel [there may be more than 1]) then check for spark and replace the spark plugs, wires, and magneto/distributor cap.

I hope this helps and good luck! Don't forget to rate! Thank you!

My Nissan 200sx when I step on the gas it cuts out

The the airflow meter can shut off the car completely, it can also stop the car from reving over 2000rpm "limp mode" to save the engine from getting un-measured amounts of fuel.
