Question about 2002 Buick Regal
I have replaced the gas line filter and air filter and checked the plugs. The problem still remains that it will not accelerate.If you step on the gas it revs but goes nowhere then you release the gas it moves slowly until as you keep doing this it gets up to speed but you do not try to pass because it has pick up.
My 02 regal was sluggish before and i brought it somewhere and they said it was the crankshaft sensor so they replaced it and it wasnt the problem then they replaced the maf sensor and that fixed the problem a couple days later the maf they installed malfunctioned and same symptoms which confirmed that it was the maf from the start so dont fall for there ****

Check your catalytic converter, my 02 was doing the same thing and the cat was clogged. If you want to test the problem yourself, you can disconnect the exhaust from the manifold where the two exhaust manifolds merge into one exhaust pipe and take a test drive. You only have to crack the pipe open about 1/2 inch, it will be VERY loud. There is a recall on the 02 catalytic converter.

Have you tested the MAF sensor, disconnect the MAF sensor and see if the problem goes away, if it does replace the MAF. Disconnect the battery to clear the code.
