ok my car has been feeling weird lately. I put the pedal down and it feels like i lost about 25 HP. Its decent when i put the pedal down a little..

but when i floor ( step on it a lil) the car kind of hesitates and then the power comes in. It kinda of stumbles or somthing. Like stumble-stumble- then the power kicks in. (yet it doesnt feel like it pulls like it used to?) It feels like when my spark plugs went bad. But i got those replaced while ago.

what could it be? I just got the tranny serviced 2 weeks ago, the car tuned up 2 years ago (spark plugs and all), and the air intake is fine? Please tell me what it could be. THanks in advance.

 

If it runs fine at part throttle, but stumbles on WOT, I'd first suspect a fueling problem.

Check your fuel pressure. Good luck!

 

some1 told me that i should change my fuel filter. How would i do this?

 

was ur a/c on it takes off about that much hp but it shuts off at wot the only ything i can think off is that it takes a second to shut off then u get full power its worth a shot to just try it with the a/c off.

 

Did you notice if the problem gets worse with an increase in temperature?

I have the same problem, mainly from 1100-2000rpm's.
It seem to get worse with heat.

I'm going to replace the wires first and see if maybe that's it.

 

The filter is right under the drivers side underneath. Its real easy to change.
