Need to check fuel pressure and fuel filter first. I think you will find your problem there.
Pushing on the gas pedal
Intake manifold gasket
There is no need to reset it there is way to reset it if the valve is a problem it has to be replaced I think there is another problem but I have no way of knowing what it could be
If this is a general noise, it could be the transaxle. When you are accelerating, the engine is pushing the gears, and when you let go of the pedal, the vehicle starts to shift back down. If this is an engine noise, it could be predetonation or a valve problem.
If your 1999 Acura TL starts well but develops a problem when you accelerate, the problem could be with its transmission.
Try Putting It Into Gear!!!!!
Sounds like a brake problem. Need to pull wheels and check the brakes.
YES. Bad fuel pump pressure can cause that problem too.
possibly a problem with the torque converter locking up, or could be something as simple as a vacuum leak
If the 1999 Suburban noise is a sort of loud banging noise, the problem could be that the engine have jumped time. Jumping time would cause the noise and jerking in the engine.
vacuum leak?
I experienced this same problem before too. The security system could be the problem. The imobaliser shuts of the car if it thinks there is a problem with the ignition(if it was hotwired).
