Riddel me this... new
#1298640 - 08/11/06 05:45 PM

And my problems continue. I don't know how much longer I can put up with this...

My car was missfiring (cylinder 6) and running lean. So I did a complete UIM/LIM rebuild and replaced that injector. I also replaced plugs and wires. The car continued to misfire... so I brought the coil to Autozone and they said it was bad. So I replaced that too. Of course, the car still misfires. So that is where I am at with the misfire.

Also, when my key is turned off, the car continues to run smoothly. You cna rev the engine and it run fine. Except the RPM gauge reads 0 as soon as you turn the key to off. Sometimes after this happens, the door switch lights will stay on and you can also turn on the air and heat. So I replaced the ignition switch, but no luck.

Any ideas before I go crazy!?

Sounds like a bad wiring harness.

Sounds like 2 separate problems. A power relay may be hanging up keeping the computer alive. The tach runs off of the PIP signal that runs the ignition. First time I ever seen a computer driven car do this! The computer must still be on because it fires the coils and injectors.
When an injector goes out the rest of the bank goes rich because of the air being pumped via the dead cylinder. The oxygen sensor says lean and the EEC tries to fix it.

Did you replace both Injectors 6 and 2? Or did you switch out the injectors and found out it was Injector 6 which was the problem?

I feel like this is an episode of Unsolved Mysteries... I still can't figure out what is wrong with my car and its time for an UPDATE.

As for the misfiring, I am going to try and switch the injectors around so that the new one is in the #2 position and the #6 has an injector that definatly works.

As for the never shutting off, the new ignition switch did not fix the problem and the relay seems to be fine. But it seems as if the relay is always on because when u disconnect the battery or the relay, it clicks on as soon as either is reattached. Is this normal? Should it always be getting power?

My big question now is: Could this all be related to a bad computer?

For the ignition issue, check the wiring under the Power Distribution Box next to the battery and Passenger compartment fuse box left of steering column under dash.

Phew... finally a response. Thanks Tony2005.

One question though: What would I be looking for?


By the way, I found this: http://www.contour.org/ubbthreads/showflat.php?Cat=&Board=trouble&Number=1115796&page=&view=&sb=5&o=&fpart=all&vc=1

SAME EXACT problem, but I don't have a remote starter.
