Wont rev past 3000 RPM while driving.
The car is an 87 camaro iroc, when i start it up it has trouble like sputters then idles fine when its cold. I went to take it for a drive and it wont rev past 3000 RPM when i hit the gas itll just drop off, no power at all. i get the feeling its fuel or spark or something else.
i honestly cant remember the last time the filter was changed
but im going crazy right now i just dont wanna pay an abundant amount of money to get a shop to figure out the prob.

Re: Wont rev past 3000 RPM while driving.
Yup, got the same problem on mine, won't go past 3000 rpm while driving hard. Power just drops off. Idles a little rough but is fine when it warms up. 84 TA, 305 carbed, automatic. I'm wondering if it's a carb needing to be rebuilt issue.

Re: Wont rev past 3000 RPM while driving.
Yea! i just did a tune up 8mm taylor wires and NGK plugs. They were the universal wires but i fixed the ones i screwed up. when it gets to 3000rpm, itll go to about 3500 if i just step on it and the needle on the tack will flutter and go no further. it seems like engine is not getting something

Re: Wont rev past 3000 RPM while driving.
Is it popping or backfiring? Is your convertor or exhaust plugged?
