accel problem

[winnipegcamaro]

I have a 2002 v6, ive been having some problems with accelerating and am not sure where i should start in figuring out the problem. idle is fine, reving when not in gear is fine, while in gear and pressing the pedal i have power and pull up untill round 2.5-3000 rpm, and for some reason it kinda cuts out there almost like a redline, it just doesnt really pick up speed or i cant feel the torque. any suggestions on where i can begin? coils, or fuel injectors, electrical? i only have 60k on it so im pretty sure there is no engine damage or anythign like that.... i hope well thx hope this is clear enough

Re: accel problem

what mods? when and what was your last tune,
and most important, what have you found by using the search button?

Re: accel problem

After checking the obvious things I'd start with fuel pressure when the engine is under load. My fuel pump went out at 49K. Yours could be providing enough fuel until you get to those RPM's when accelerating, because the engine is under load. After that, there isn't enough fuel to keep it going. Just a thought........

Check for a clogged catalytic converter.

x2 after running it for a lil while look under it at your cat, see if it's glowing red or even bulged.
