Welcome to the Michigan FBody Association website.
The Michigan FBody Association is a centralized website for FBody enthusiasts to discuss what's going on in the Michigan area. MiFbody.com was created to allow for an easy one-stop place to find out what's going on in Michigan as far as FBody events, to find out what clubs are available in your immediate area, and for an easy place to post classifieds for items you want to sell! Our goal was to create a more close-knit community of FBody enthusiasts in the state of Michigan, and to bring Camaro and Firebird enthusiasts alike together for some amazing FBody events!
The most important thing to know about the Michigan FBody Association is that we are NOT a club! The Michigan FBody Association is open to everyone, and is a community. Thus, we will have get togethers, casual cruises, events, and such like that, but this is not an exclusive club and it's 100% free to join this site! So what are you waiting for? Register now!

have your ecm checked. Make sure your opti harness is plugged in and connections are good and clean. Something is a little bonkers, low voltage @ the fuel pump but, voltage overcharge condition. The worrisome one is the 55, ecm error. theyre pricey. clear the codes and retry it.

The PCM in this car is from Pcm4less it's not mine only had it in for maybe 25 miles could the Ecm code have been from the previous car? Also I still have my stock untuned PCM could I swap them back out? Also I bought 02 sensors hope that was the problem
Seems to have spark. Also I drove it today and in OD it hesitates at 4,000 rpm but if I shift it it runs through 4,000 no problem I have no clue what's going on. Sometimes it idles really rough others not that bad. But I noticed at a constant rpm it sounds like it cuts out.

This thing is really pissing me off just did longtubes ory lm2 converter shift kit and PCM now it doesn't run right and the wife says no more money into the car. Great now it will sit till next year
So what was the reason for changing the pcm? Tune for the converter? Do you still have the stock one you can swap back in?
You changed a lot of things at once, we need to eliminate a few things on that list.
Another thing to check is your battery straps and grounds. A bad ground on these cars can really screw things up. My car was stuck at a buddies house for a week not wanting to start/running like crap over a coincidental ground issue one time. I thought i had fried my PCM because i had been tinkering with it, but after getting another out of a junkyard i found it wasnt the problem. The ground block on the top of the fender can be a source of problems.

Yeah it was tuned for the mods including the converter. I do have the stock PCM still I was thinking about putting it back in to see if it clears up. Will the car run fine with the converter and a stock tune? Also when I burnt the plug wire it was a stock wire, I then changed all the wires on the passenger side to the MSD wires and it has not ran right since.
People will disagree with me but i had nothing but problems with aftermarket wires. Had both taylors and msds, and my car ran like garbage with both of them. Took me 2 years to figure it out because in both cases i was convinced wires couldnt be the problem. Its not that i dont think MSD or taylor makes a good product, but my experience has shown me our ignition system is uniquely fussy and doesnt like to be tinkered with. Seems like if you change the wires, or the coil, or whatever else you disturb the balance of the overall system GM apparently was able to achieve. Right now the only thing thats changed from factory on my car is the heat range of the plugs for my additional compression. Everything else is GM spec and Ive had no problems for 7 years now. Car is cammed shifting at 6300 and its been drag raced, auto-x'd, and road raced (continual high rpm).
You might try buying a set of delco wires with a return policy... If they dont solve your problem take them back. They are an expensive wire set, but beats having a car that runs like crap.
So I put my stock PCM in and it seems that the rough idle is gone I can Rev it to 3500 with no popping. Is it ok to drive it with the stock PCM to see if under load it changes?
