My 02 cavalier will not shift when I quickly press accelerator it just revs up but if I let off gas and I ease into it like normal it shifts smooth. Just changed transmission fluid and filter along with throttle position sensor and cleaned the idle air control valve. It doesn't seem like the transmission itself is going bad because it shifts to good with normal driving. Was wondering about the passing gear. If it has a sensor or maybe a shift sensor.

fuel pump is working but when accelerating it doesnt pump enough fuel up to the engine then it will fall on its face if it is a electric pump you may have to drop the tank if it is inside and replace it if it is on the engine replace it thats what is exactly wrong with it

It could be electric fuel pump stall. The pump isn't pumping fuel fast enough. This model may have a inline fuel filter before the fuel pump as well that might need replacing.

It could be the cat. it sounds like this could be your problem

You can manually test the egr valve by pushing up from underneath it and seeing if the spring loaded valve moves and re seats itself. If no, it's bad.

SOURCE: 2002 ford explorer 4.0 v-6 transmission not shifting between 2nd and 3rd gear

This same thing is happening to an Explorer I'm working on. It will rev up for as long as I stay on the gas - never going into 2nd gear - but the moment I let off the gas pedal, it slides into 2nd gear. It goes into 3rd, 4th, and 5th normally. I've changed three solenoids, the shift cable, and fluid/filter. I'm still having the issue. I honestly believe it's an electrical signal that's not being acknowledged by the system and not a mechanical failure. I'm tempted to replace the transmission control module, but if someone can provide a TRUE SOLUTION and not a bunch of nonsense, it would help. Once I resolve it, I WILL BE posting a solution and not a "guess". I'm working on it today, and will figure it out over the next few days, I'm sure...
