Misfire perhaps? I have a 94 lt1 formula. Ok I've had little to no issues with this car. Figures that as soon as my wifes car goes down. Mine has issues to follow. Ok I came off a little bit of a trip. When I got off the highway. It began to stumble then die. Found that issue to be my coil wire came off the coil. So all was well. Went home after doin a couple stops. Went home and put my TB bypass and 160 T stat back in. No issue. This morning I got up earlier than normal and when I started it. There was an obious misfire. Though at steady freeway speed, I couldn't notice it. This is very obvious at low to starting speed under 2500 RPM. Everything looked to in the correct places once I got to my destination. I checked to coil wire and there appeared to be a lil rust build up in the wire. Could it be that simple? This in an INT problem. Meaning at times I think it's cleared it self. Then it returns. I've replaced the wires and plugs in the last 2 years and their MSD wires. Any ideas? Times I wish is was an OBD II!! lol

Oh I had cleaned the injectors in the last year. Fuel pump couple months before that with filter. I only use top tear gas. Also no check engine light. It almost reminds me of when the timing is retared. Could this be a sign of the opti? When it's cold. From time to time it'll backfire TB side. Any ideas?

I was thinkin coolant as well. What's crazy is that its been fine ever since. I know I need to rebuild it. But I want to on my terms. But I am lookin to upgrade the opti do to it being the original. I would just like to budget it in first. Lol
