Question about 1999 Saturn SL

Open Question

I screwed up my 1999 Saturn SL 1.9 SOHC spark plug wiring while trying to put in new one. I tried to do each one separately but the saturn's have a wiring holder i just couldn't get apart to do this. what I need is from left to right looking at the engine spark plugs which cylinder goes to which coil terminal from left to right. There are four coil terminals Please help I am desperate. I can get the car to start and run but it runs really really rough now and I dare not drive it. Stalker

SOURCE: will not start after it stalls untill about 5-10 minutes

Your problem is most likey your intake gasket.They have a problems on the SOHC engines where the intake gasket shifts & starts leaking vacuum at the #1 intake runner causing a missfire on Cylinder #1.While the engine is Idling buy some throttle plate cleaner & spray throttle cleaner down at the #1 Intake runner where the intake meets the head.If engine stalls or runs rougher that's your problem.I have replaced dozens of those gaskets for tha reason!! They have a beter design gasket through saturn parts.It has a coating on it to prevent reoccurance.Also you should check you Coolant Temp Sensor,if it's ceramic it's most likely bad.Replacement is brass from saturn.Good Luck

SOURCE: Engine is skipping when accelerating

You only have 4 so better just do a tune up and change the plug and wires, but one at a time so you don't get them crossed when re-installing the new plugs and wire.
Use Platinum plugs since there good for 100,000 miles which mean less maintenance, and double check that the spark plug boots set to the plugs when re-installed.
Run some fuel injector cleaner through the gas tank for about a week to to clean out your fuel system and hope fully the skipping stops.
If your going to get all the goodys at Auto Zone, have them scan the car for any DTC codes since it's free and see if there are other issues that is causing the skipping like a bad signal from the MAP sensor ECT.
Good luck and keep me posted.

Where is the camshaft sensor located on a 1999 Saturn SL1?

If you have the 1.9 SOHC, you don't have one. If you are getting an error code for a bad camshaft sensor, you either have a bad spark plug wire (#1) or corrosion where the plug wires go to the coils.
Swap wires from cylinder 1 to cylinder 2, and see if the check engine light goes away. (This is common on the staurn) If it does, replace the wire set.

What's the difference bteween a 99' saturn sl and a saturn sl1? My 99' saturn sl wont go in reverse, what might be wrong with it?

The SL2 is a DOHC 1.9L and the SL1 is a SOHC 1.9L. They have different transmissions, the DOHC uses a 15 inch wheel while the SOHC has a 14 inch wheel. So when you are shopping around for another transmission you must get one from the same type of engine. Saturn auto transmissions seem to be problematic, I stuck with the manual trannys and had very good luck.

Where are the spark plugs located on a 2001 saturn sl

On the SOHC the spark plugs are on the front of the head (towards the front of the bumper) at an angle. You will see the 4 plug wires going to the top of each spark plug and then back to the coil pack.

On the DOHC (which is an SL2) they are directly on top of the head and vertical. Again, you'll see the spark plug wires going to the top of the plugs and then back to the coils.

Get a spark plug socket an and extension and they'll come out. Make sure to take them out after the car has cooled down, it is an aluminum head and will cause the threads to get mangled if the head is hot.
