motor surges at idle?

[andrew59]

My motor will shake back and fourth at idle? Any help

boost leak most likely.

Also do you think you can give us more info on your setup? What are you tuning with, injectors, turbo, throttlebody, etc.

[andrew59]

um i just got the gs model, its a 2.0 non turbo stock everything

any check engine lights?...like i said before,tune up,mainly plugs and wires.my eclipse doesnt have any vacum lines on it and it idles just fine.your idle air control valve might be gummed up and not working properly.the 420a carbons up in the intake realy bad on these cars so check that out

[andrew59]

yes the check engine light is on..and sometimes it semas like it want to diewhen i go from reverse to forward?. im guesing the wires and plugs havent been changed on it ever. ok so do i put some senative to clean out the carbon?
btw this car is a fn pile it looks clean on outside but underneath and the motor is shit!!!

Same with my 1997 gs. If you look in my avatar. CLEAN as F*@# but under the hood is sh!t. I totally agree.

smells like a vac leak
