2004 Pontiac Grand Prix GT jumps when I try to give it gas. Took it to advanced got them to run the codes. Oxygen sensor came up so we replaced the one behind the block. Still having the same problem.
Engine light is on and has been for years
While idleing I pushed gas pedal it almost stalled out like it was flooding
Have you changed the fuel filter?And all so check the fuel pressure on the fuel pump,may be going bad.
If it sounds like its stalling at higher revs that may be normal. Don't forget it has a rev limiter so if you step hard on the gas at idle it will hit that limit and sound like its stumbling.
