yesterday when i got off from work at about 9 30, it was pretty cold around 32, i started my car and let it warm up for a min or two, then drove slowly still letting the car warm up, but after like 2500 rpmmy car would just totally like bog, i'd have the pedal down to the floor and it would slowly accelarate, going slowly trhough the rpm range, and even after it warmed up, and the whole day today. Does anyone know what the probolem could be?

Thnx in advance

I have an auto and it does the same thing. Only mine is not a everyday thing. Some days it does it, some days it doesn't. Its only from 2500-3500rpm, before and after is fine. power seems really low, struggles to climb rpms. except for a little hesitation off the line unless you give it a lot of gas.

how is the idle? I've had a similar problem with a rough idle. Usually something in the fuel line or dirty injector. A bottle of seafoam fixed it once...and another time, I just pushed it to 55mph...and it got "unstuck"

I'll try the seafoam--just did that a couple months ago as well. And the injectors are only about a year old. Replaced the stock ones with Pythons last year.

run it through your tank.....injectors won't clean through the booster.

I only had white smoke....so I guess there are different "levels" of carbon buildup.
