ok im assuming this is a fuel issue..i could be wrong so any help is appreciated. i have an 89 camaro with 305 tbi...now the car seems to run fine but after driving for like 10 minutes it starts to sputter a little bit, mostly when i give it some gas. its done it for about two full tanks of gas so i would eliminate "bad gas" i also changed the fuel filter yesterday and same problem. tried a fuel injection cleaner and still the same result. if anybody has an idea of what this is i would appreciate it. thanks

 

Get a fuel pressure tester that you can tape to your windshield. While driving around when the problem happens look at the gauge for low fuel pressure. This will eliminate any guess work before diagnosing a specific problem.
