My car developed a fairly nasty ghost. It basically runs like the leading isn't firing(revs slow, no power, and the misfiring exhaust note). It ran that way for about 2 days and one morining it started to clear up. It hesitated alot bat had times of power and smooth rev. It is back to running like crap after sitting overnight.

The car has no airpump or cat, no 6port sleeves or actuating rods, no ACV or OMP(premix), and no fast idle butterflys. It has ran like a champ until this occured.

I have replaced the plugs, wires, cap, rotor, swapped in igniters and coils with no avail. I checked the timing but found a another problem. I can see an actual miss with the light. I try to line up the leading on the mark and I can't advance the timing enough. The 2nd Advance diaghram mounted to the side of the distrubutor catches the mount on the top of the engine for a hoist spot. Is there a difference in non-point distributors with 1st gens. I don't think it should catch like that.

I had plans to try regrounding the ECU.

Please help.

 

not sure that this will help, but is ther any chandce that a fuel pressure regulator could be givingo you thos problems. There are three different ones wiht the fuel injection setup, two bleow intake manifile and another in or around that area. I havea gslse an d those pressure regulators casued me to finally go carb, not sure that your problem can be cause d by one of those but maybe??

I dunno, you said you "swapped igniters". Does that mean you replaced them? or swapped positions? I always thought an igniter was either good or bad, but found out differently on my SE. They can be intermittant. I had exactly the same problem on my SE and replacing the igniter cured it.

 

Yeah I was thinking the same thing as zookeeper. On my car though, I actually replaced the ignitors with good ones and still had intermittent (off for 5 mins, on for 1) spark. In my case I just pulled the whole distributor out of my parts car. But clearly those contact points below the rotor or something else in the distributor was broken on mine.

 

Well she is fixed.... I spent most of the day going over everything. I swapped in another distributor, tested the igniters by the Haynes, and checked the airgap on the pickups. It turned out to be 2 bad spark plugs. I couldn't believe it myself but both the plugs in my rear rotor wern't firing. Imagine my suprise when I switched spots with the other 2 plugs Anyway, running like a champ again.

Thanks for the help guys!
Peace!
