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!

Hey guys, my car ran fine monday. Then on Tuesday I fried a wire so I replaced the wire and the plug and it is still backfiring not as bad but definitely lost power and rough idol it's a 94 z I just put headers exhaust and had a stall put in. Got the car back Monday it ran great. And now this Please help so much money into it this year and it looks like it will be sitting this summer.
Check the plug, heck just replace it. Check the rest of the wires. The best way is to look at them at night while its runing. So now just to clarify. Is it a mis or a backfire,? Also check the firing order, make sure the wires are correct and fully seated.
I'm not familiar with the LT1, but when my 1st gen had backfire issues it was related to the HEI. I'd look at the optispark and ignition timing.
This is one of the biggest problems with the Opti system. Its buried under the water pump. And the computer controls the timing. without a bunch of electronic test equipment, its a bear to diagnose. Even to change the cap, you have to remove the water pump.

It has superconductors on it now. The wire I burnt was #6 it was a stock wire. It does seem to run better with the new wite and plug. But still backfires just not as bad
LT1s are very fussy when it comes to plugs and wires. Do not run a larger gauge wire than stock and run a factory heat range plug gapped on the conservative side. (Big wires, big gap = more resistance which the opti hates).
I personally use nothing but AC delco wires and NGK TR6 plugs (use TR55s on a stock engine). Check the gap on them and if anything go narrower than the factory setting. I dont think its coincidence this problem started after you burned a wire. What kind of headers did you get if you dont mind me asking?
One of my plug wires would always end up resting on one of my headers and then would arc to the header. I got those Kevlar cover things and those helped but still burned through on of those... I eventually just upgraded to more bendable wires.. But in the process of all of that I think one of my o2s went bad. Once I fixed that, it ran fine.

I have my wires in the stock location, but the stock looms are removed and the wires are held in place with zip ties. Works perfect ive never burned a wire. But some headers dont have enough room to do this (why i asked which ones he had).
