power loss in accelerating?

[ridnEclipse04]

i just got my license and inherited my dad's 01 eclipse gt. most of my friends with their cars when they're racing shift at redline. when i'm accelerating in the eclipse there's a sudden power loss at just over 5000 rpm. is this just the shifting point in that car or is there something wrong?

I'd say go to a dyno and do a baseline of 3 runs. That will give you a graph of your power curve so you can see what is going on.

shouldnt be check the sparks...

i usually shift about there. the max hp is reached around 5500rpms but it seems as though the engine is starving for air. thats why i shift at about 5000

if you wanna go higher, i think you need an intake, w/ the stock system on there, the engine doesn't get hardly any air at all, just look at where the inlet is

ya i've had the problem fixed for a while....i took another look in the engine bay and it turns out the two screws holding the scoop were gone and it was rising up when i would floor it and suck on the hood. I was mixed with depression and happiness that it was so simple of a problem

they messed w/ teh screws at the dealership and mine did something similar...it sux, and i was already missing one screw so i just ripped that little bit off and left the airbox

[ridnEclipse04]

ya i grabbed two screws out of the garage and jammed em in there since im waiting on getting the money for a new intake anyway

[eclipsed4utoo]

i could have told you that to start with

[ridnEclipse04]

well it would have been gladly appreciated

[eclipsed4utoo]

well if you would have explained your problem more thoroughly, then i would have. when mine started doing that, it was happening at about 4000rpms

Hey since we're on this topic...I have a problem with acceleration sometimes like...when i'm accelerating, then take my foot off the pedal to slow down from the car in front of me or something, then go to accelerate again, my car with suddenly lurch forward! Or if i'm sitting at a stop light then go to accelerate, my car will sluggishly start off sometimes, but fly off other times...anyone know why this all happens?!?

5 spd?

its trying to shift to where you need the power, you are simply putting your foot on the gas too hard, try easing onto the gas after braking
