Engine Performance problem
1989 Chevy Suburban V8 Two Wheel Drive Automatic 154000 miles

my car had to be jumped and once it was running, after about 10 minutes, it felt like the gas wasn't getting to the engine, it would sputter and pop. I would floor the gas pedal, it would take awhile for it to move, then it would run fast, then slow down, floor it again and the same thing would happen. Is it a sensor, fuel pump or bad gas?

not sure if this is it, but mine had a similar problem, ive got an 86 and the carb went bad. similar symptoms. once the engine got warm enough it was alright tho.
