Anyone here a C4 guy?
 

I have some flaky shit going on with my '94 C4.

It's a later 94, and thus actually is one that has an ODBII connector (thank goodness), and it's coding "36 - ignition system problem loss of high res pulse signal"...which would suggest a bad opti...but the fucking thing is kinda acting stupid all around...like occasionally throwing other codes, lighting the ASR Service light, and even the fucking A/C went to the zoo for a bit, until the car was restarted.

It spits, sputters, and acts up...and then the "check engine" light comes on, and she runs fine :scratch:

I think it may be a bad wire, or connector, or maybe my ECM is hosed.

Anyone had any shit like this?

:bash:

Run through the wiring harness and check all of the sensors. I seem to remember my uncle having the same sort of trouble and he had some wiring issues. Dont quote me, cuz I am not positive. I will see if I can get in touch with him tomorrow.

Thanks, Tom.

I clicked on this thinking you wanted something blown up :lol:

Faulty MAF? IIRC, that was a fairly common problem.

Tracy (GRex) could probably provide some insight as well.
Oh he of the cursed C4. :lol:

I was deliberately not going there :lol:

I don't know about the C4 specifically but in my experience when a lot of different things are going wrong like what you describe you may want to check your grounds. A faulty ground can cause all sorts of seemingly unrelated problems. Check them all and clean or replace where necessary before dumping a bunch of money in to the car.

If I can't diagnose the fucking thing, that just may be an option...

:bash:

Me too. Though that could be the ultimate answer. :lol
