·i have a 1994 firebird forumla with a six speed. After a minute or two the engine will begin to stumble really bad, if i push the throttle to the floor it will open up and run, but from 1000 to 3500 rpm it stumbles. I checked the fuel pressure and it's running at 35 psi, which is almost ten under normal. Also the the spark plug wires are arcing to the head, but i've replaced all the wires, and i check them all the time to see if the headers have burned them. I've had the module on the coil checked, and it was fine. I checked around the coil and there's no evidence of it arcing. I also checked the fuel filter, and it checked out as well. Everything seems to be in order, but even after changing spark plugs and wires it still arcs. I've read alot about the optisparks going out, and the symptoms seem alot like what i've experienced, but i wanted to make absolutely sure before i go taking the water pump and all that crap off, but i would really appreciate some help with this.
.... and yes, lt1's came in 1994, they actually came out in 1993, at least to the f-bodies *camaro's and firebirds*
