sounds like you have vaccum leaks, also try running straight header maybe your cat is clogged up and causing too much back pressure.

i would definately read my article on fixing an erratic idle.. found here or found by clicking the articles tab up top.

it has no power because you have some serious tuning issues.. i suggest a good fuel management and 2 hours of dyno time. do you have s2 cams?? what cam gears??


Found my problem it was the intake manifold gasket it was leaking water out and inside of the #4 cylinder next to the thermostat so i took it apart replaced the gasket new OEM and whala its all better now i feel power and torque not much torque but i guess thats normal IDLE is purrrfect about 700-800 rpm it does shake alittle but i guessing hasport mounts and missing the front one so that alright.........I did get this dumb error code on the ECU #17 the godamn VSS i guess im going to have to wait till i can get my ECU reprogramed to eliminate most of those pesky sensors like speed limiter oxygens, red line to my need ??????????? Do you know if by chip the ECU it will get rid of this VEHICLE SPEED SENSOR
"Thankz All" and remember to check your leaks ........ :thumbsup:
