You're welcome. The DIS Module is the Ignition Module on your 2.3L DIS system, so I'm not sure what you mean...

 

My bad... I meant the two ignition coils... Are they grounded through the mounts as well?

 

That's a great question, I'm not sure off hand, but I'll see if I can came up with an answer, as I would like to know myself.


On edit: Thinking about it, I would have to initially say "no", the ground cannot be through the mounting holes, since a ground "switch" is what operates the coils, opening and closing the primary circuits, causing the secondary coils (and hence the spark plugs) to fire.

This is a quote from the DIS/EDIS article I posted a link to above, which is applicable to your 2.3L DIS system:
But I have to think also that just because there is switch involved, that does not necessarily mean that the ground still can't go through those mounting holes/screws in some fashion...

 

Thanks for the replys. In either case, I made sure the mounting area and the screws were clean before I re-installed the coils and the DIS. Much to my dismay, though, after everything was said and done, I had inspected and cleaned virtually EVERY electrical connector I could locate, I un-bolted and cleaned every engine-to-body ground I could locate, and the condition STILL exists!! (ARRGHHH...). So now, I think I am convinced the condition posted at the top of this thread is caused by a fuel delivery problem - either too much, or not enough. Now, when I start the engine, it runs fine at idle, but any quick acceleration (still in park) it boggs and nearly dies - until I back off the accelerator, then it's back to idelying fine. ALSO... Seems to be running quite lean - the smell is obvious. Would a bad fuel pump cause the problem? What about a bad fuel punp relay? Or the fuel filter? ANY MORE IDEAS? ANYONE??

 

if you think it is running lean, then get a vacuum guage and check for vacuum leaks.

 

Throttle position sensor, dirty MAF, fuel pressure regulator, bad vacuum leak, not necessarily in that order.

 

Your best bet would to put a fuel pressure guage on it and rev the engine. Watch the fuel pressure, if it drops then look for the problem. If that is ok the look for an electrical problem. Have you replace the the PCM power relay? That would explain no error codes, also if the fuel pressure was dropping I would think you would get some error codes, Lean cly, o2 sensor etc. Also, do you get any dash light flashes when it stumbles?
