I have a 3.8 v6 in a 81 grand prix and im having a problem accelerating in it. The car idles perfect but when you barely press the gas while drivin it seems like the motor gets weak and when u press the gas to the floor it doesn't really do nething. But when I press on the gas while its in P or Neutral the motor will run normally

The advise about the cat is something to look into, before you do any possible damage from heat backing up. My moms caprice had the factory two stage cat block up, you could hold your foot to the floor and not get over 40mph.

Im going to try to run the car today since I put a new carb on it and a new water pump because it was over heating. If it still wont get up to speed i guess im going to have to get some pipes. What mufflers sound the best on a v6

Could it just by chance be the fuel filter??? Start there, then do a backpressure test.. that will tell you if it is the cat, should have about 1.5 lbs of pressure at 2000 RPM.. Hope it helps...
