So latley it has been getting alot worse. After a stop i will go push on the gas and it will take a few seconds before even relizing i pressed the gas pedal. I can step on it and it wont go, i can hold my foot opn the gas pettel and sometimes repediatly step on it and it wont got for a while. It happens pretty often and could be quite dangerous. Any advice?
Werid throttle response

I can see that you have a 2000 Passat 1.8T, so that's a Drive By Wire (DBW) throttle.
Have you cleaned the Throttle Body? It's simple to do, and may be all that is needed. Instructions here.

Yes it has been cleaned recently, I remeber reading somewhere some brake light fuse or somthing needed to change when something like this happened but i dont remeber i could be totally off. I have spent too many hours reading on here lol

I made mine considerably better by cleaning the air intake temp sensor, located just after the throttle body. This was about a year ago and it's gotten worse since, so I'll have to do it again. This seems like a really crappy design.
I used some spray carb cleaner and a rag.
I'd love to hear more about this brake light thing.

If you have access to a VAG-COM and cable, even the free one, you can hook it up and monitor the Throttle Position Sensor as you press the accelerator down different amounts.

It's one of the POSSIBILITIES. You push the gas pedal, which has a sensor that tells how far it's pushed. It transmits a signal to the ECU, which reads it, then passes it on to the throttle body. At the TB, the solenoid opens the butterfly as much as the ECU has told it to. A sensor also reads this position, and reports back to the ECU.
Open and shut, right? Wrong. Hence why you need the VAG-COM to test. It could also be a bad cam sensor, or clogged injectors, or a leaky vacuum system. You push the pedal, the problem causes the engine to bog or hesitate, and THEN off you go...
Why do you think so many old-school mechanics yearn for the good-ol' days of carburetors? Those problems were always easy to fix!
