OK.. What is involved in a Delco conversion? You mean an ac Delco unit? I see them at the same stores, maybe $40 more, with a one year warranty.. Are these what you mean? What is being converted if not? The coil with the three separate coils, that kind? And what about the ICM?

Ran ok for a few hours, then started a different type of miss. Fully warmed up, two flat cylinders. Had it towed to the mechanic, he tested a few things, then switched around the coil and ignition module connections, it ran better. I just had him change the coil a few days ago.. Told me how to check ...

The latest is.. The crankshaft sensor! It was loose.. Maybe not tightened properly when I changed it during the recent engine rebuild. The pigtail connector also seemed beat up and had some silicone type hook smeared around the end wires.. We changed that and the cs sensor.. And he said it fixed the ...

So, my mechanic put the car on some kind of fancy scope, showed me like an occilloscope wave readout, that seems to show the 3 and 6 cylinders are having a drop in voltage or something. Based on some other readout data, he is leaning towards an internal engine problem causing low compression, such ...

Hi.. Yes just spoke with current mechanic checking on it. Said the maf sensor and throttle body sensors were reading properly. My question, is what sensors component should, etc could be messing up with the car being cold? Once it warms up runs better without as much hesitation... We had replaced ...

Still dealing with this problem. Brought it back to an electrical auto specialist, at least that's what his shop sign says. Lol..he seems lost too..had the car a week. Talking about starting with replacing the battery and alternator? I explained that the battery has like 200 miles on it. The ...

sorry..this is a most confusing situation , and explaining it all chronologically has been a pain in the arse too...The master cylinder and power booster on the car presently were purchased new from Oreiily auto parts here in LA, for a non ABS Pontiac Bonneville model...we got the junkyard cadillac ...

One other thing, if you might know. Can the brake pedal rod, that connects from the booster to the pedal, could the length of that be changed to move the pedal up a little, so it doesn't start out sitting so low? Besides the soft pedal feel, the pedal may be sitting a bit low. My mechanic friend ...

Ok then. So you are recommending, Mr. Jolly, that I replace the master cylinder, and run new lines to the rear. I can get my guys to do that..let's see

Actually, the two rear lines aren't split as they come off the MC, but rather are joined together into one with a T , that goes under the car to the rear...

I read on other posts that reminded me that the original ABS set up had three brake lines coming from the master cylinder, one for each front wheel (discs) and one to the rear that gets split halfway back under the car, with a line going to each rear wheel. The way my conversion was done, I have two ...

No new codes. It starts right up, idles ok, if cold stumbles and misses once step hard on throttle. If early can be ok. Once warms up still can only give it an easy poke with the right foot.. Otherwise misfires again... Gas is clean.. New rebuilt Bosch fuel injectors.. New fuel filter.. New sending ...

The new mechanic working on it seems to think it is electrical in nature.. He's had the car going on 4 days and so far nothing has been found definitively...

Yes.. I think it was bled properly. The latest mechanic that is going over it did a power brake bleed. He agrees that most likely the brake line set up is at fault. Think he will run a direct line to the back drums and do away with the t set up it has now. Actually has two T set ups.. The original ...

No, brake pedal and feel stay low and spongy...

Hey Jolly ...I don't understand your last sentence of your reply, can you restate it please?

Doing my best to keep my Bonnie humming.. But, almost three years ago we did a conversion from abs to standard master cylinder /power booster set up.. And from day one I had a real mush feeling to brake pedal. You step on it, yes it stops.. But pedal sits low and by the time you apply them feels ...

Hi.. The catalytic converter is maybe 15 months old. Maybe 1200 miles on it..? Had to replace it to pass my smog test here in ultra strict California last year.

Hi thanks for your reply. Some other factual tidbits.. The sputtering would occur just about at 2000rpm.. It now throws a code 22.. The TPS.. Which we just replaced today.. And it didn't change the sputtering.. My mechanic friend will return tomorrow and adjust and /or check the wiring... The spark ...

Hi everyone. So we did the engine rebuild..sorted out some heater pipe issues to the throttle body, actually bypassed that feature as my pipes were bad and I couldn't find a source to get new ones. Not sure if it has any tie in with my current symptom.
Car starts right up, idles ok, but once I step ...
