I just bought a 94' firebird v6 3.4 liter from a friend the car sat around for a year then he got i to run but with a rought idle. Wen the car first starts the idle is rough and then wen it gets warmed up it's fine! i Replace the IAC, Ignition controle moduel, 3x crank sensor, and computer. I also had the injector flushed and cleaned. Before i bought it the fuel filter and tank were replaced and the lines flushed. i also cleaned all the grounds and checked the fuel press and it was fine.......so what im asking is there anyone else out there that has any idea what might be going on and if their is any way to fix it!...please!
