weak engine
my 91 305 TBI is real weak once the car warms up to operating temp. I've changed the plugs, the cap, rotor, air filter, oxygen sensor (bosch), the wires were ok. I also retourqed the TBI to intake bolts. My car can't even chirp em off the line anymore. Its a 91 camaro rs with 80,000 on it. Any suggestions? TIA

Mine is bad about starting off in 2nd gear after it warms up unless I am at a COMPLETE stop for several seconds. Pull shifter to Low 1 and see if that is your problem.

well, Its not starting in second, its just lacking alot of HP. The LO3 is rated at 170hp, but right now it feels more like a soft 120hp. It never used to be this weak, even 1000 miles a go it was strong. Has anyone ever used bosch O2 sensors before, any bad results? I saved the original, I'm thinking about putting that back in for $hits and giggles, I really can't think of any thing else. It doesn't set any codes, The intake is fine, WTF? I'm not looking for extra power, I just want what I had back.
