Please i need help!!!

[Wesley98eclipse]

Well, I bought a 94 eclipse gs-t, and the guy told me I need a coil pack and knock sensor to make it run. Well of course it did the exact opposite, it will start up but takes a few seconds to make it start and I have to press the gas to get it to stay idling,also when I try to rev it up it will not rev past 3000 Rpms. Also it takes a while to get it up there. It will idle fine without the MAS unplugged but will still not rev up above 3k. I don't want to waste anymore money, please help me....

boost leak test may give you an answer. always worth a try

 

[Wesley98eclipse]

Yeah I havent tried that yet, I really should though, I'm just hoping it's not something internally

Yes boost/vacuum test usually is the best place to start when referring to rpm build up issues.

My car had that problem once and it was the throttle position sensor came unpluged... check that or just replace it too

do you have have a pocket scan ? they sel at any parts store for like 50 bucks and that will give u all the codes because im sure you have the check engine light right.

Have you put a timing light on it?
