Car seems to be way down on power?!?!?! Cause?

[wanta5.0]

The last few days the car seems to be way down on power. There are some days when it feels slower than others but the last few days it seems really slow. Could it be an exhaust leak? I don't hear one but I don't know what else it could be.amnit: Any ideas?

car making any weird noises? check spark plugs or anything lately? you'd hear an exhaust leak, mine has one since a bolt walked off the H pipe...it wouldn't cause the car to turn into that much of a sled.

It only has 25k miles so it shouldn't need plugs. No noises.

sounds something like an old volkswagen beetle... you can really feel it when you are on 1-2 gear going like around 10-45mph, it usually happens when you have aftermarket headers that were unproperlly installed, or when you have an x-pipe and the gasket has gone bad... I have one right now from a flange gasket(between passanger header and xpipe tip) or at least that how i believe its called.

Could be alot of things.
Used to it so it doesn't feel as fast.
Bad fuel.
Battery voltage low.
Dirty MAF.
Clogged airfilter/clogged inlet to airfilter
ac/defroster on. ( I can feel it when mine's on)
Did you forget to release parking brake (seen it happen)


Or you could just need to do a good double check make sure everything is tight and plugged in.

is there a loss of power with an exhaust leak? how much to repair?????

Well I still don't know what it is. Another thing I have noticed at the same time as the power loss started is that it kind of jerks on the 1-2 shift and the 2-3 shift. It feels like the damn brakes are on. Maybe its bad gas. Any more ideas.?

do a compression test

any drastic weather changes? what part of the country are you in? i know there has been some reported lower quality gas getting out in the eastern part of the country(CA has its own gas supply cause of smog). your fuel filter might need to be replaced.
