When I rev my engine to 3500-4500 my engine acts sluggish like its struggling to rev . Its a really unclean rev. I have plugs wires 10mnths old. A few pump 3mnths old coil packs check out. Air filter clean. New tps sensor. What could it be??? :?

Cleaned your TB and IAC lately?

Idle air controler eh? Never would have ever thought of that.... good call prolly that..

Where is the IAC?

by the TB. do you have a chiltons manual?

Yeah its not in there.

not to be a pain, but why would the IDLE air control valve be making his 3500-4500 range slugish?

anyhew, if you really want to clean it, it'* in the throttle body...

as for the reason your 3500-4500 is sluggish...

are you doing this while driving (sorry, i have to ask)? if this is in neutral, than your engine would be wise not to let you rev it that high. if it'* while you're driving, then we're opening up a can... of worms that is.

how long since the spark plugs themselves were done? you mentioned the wireset, but did you get the plugs while you were at it? when you say that the coil packs check out, do you mean you've swapped them with another car?

This is while neutral... its not that its not letting me rev that high.. its a restricted sounding rev. Yeah and I did do the plugs when doing the wires.. who doesnt.

i can find you a few

i've seen some strange things done, and since i don't really know ya, i had to ask

does it hang like that when you're actually driving?

matt

yup sure does hang. :?
