My chevy 1987 chevy Scottsdale with a 350 tbi sometime runs smooth then sometimes runs like its running with half the power or less like it has bad gas or something. I have replaced the fuel filter, oxygen sensor, air filter, it doesn't matter which tank I run it on, I've used fuel dryer (Heat) changed pvc valve, could be a injector going bad? They seem to be spraying fine when I look at them but that has been when the engine is running fine. Doesn't matter if the truck is warmed up or not it can run fine for some time then out of the blue run so bad I have to keep it floored to keep it running also replaced cap and rotor.
have the same problem?
