Rough Racer happened in 1990.
why is my 1990 305 gmc idling rough when on the gas peddle runs great
YES! If you have tried a major tune up to include: spark plugs, distributor cap , rotor, wires, and fuel pump and the truck still idles rough and stalls at stop signs then it is the TFI ignition modual located on the side of the distributor.
What would make my 1990 camaro run good for 30mins then it doesn't want to start&runs rough& jumpy
YES!
my 1990 is doing same thing i dont know whats going on yet? have u figured yours out?
Check the fuel filter. If it is the original, change it. If that doesn't help, find a mechanic.
there's so many things it could be, but I would probably start with changing the fuel filter, and see where that leaves you.
