i have a 87 camaro 2.8 v6 when i get on the gas to speed up it sputters a lil and keeps going till i come to a stop and then it is fine i put 93 octane gas in it and then i just yesterday put 89 because of rising gas prices. I am guessing it is the fufel mixture at least i hope that is what it is. what else could be the colprut of this problem. I also just a couple months back put flowmasters on it.

TIA

 

You can mix 87 89 and 93 and You will never know the differance. Your problem is not gas. It could be a variety of tings wrong. Any engine lights? Could be a faulty maf, TPS sensor, or even a miss from a bad plug or wire. Cap or rotor?

 

no engine lights that i can tell where are the plugs located on the 2.8

 

put some fuel injector cleaner in the tank and im going to change the tranny filter and fluid the one thing i just now relized is the tranny sometimes jerks when i get on the gas when changing gears when in overdrive and drive. what could be the problem i have checked the plugs and they are good so what else do i need to check if i can't fix it off to a pro it goes friday morning.

 

Did you try the fuel filter?

 

Heres a list of common culprits:

Fuel Filter
MAF Power and Burnoff Relay
Cap/Rotor
EGR Valve

More Serious:
Fuel Pump
Vaccum leak
Injectors, although uncommon, our cars are getting old and they foul out.

Hopes this helps
