does it surge through the entire RPM range? or just idle?

mattdel

no it shouldn't. unless the distributor is in wrong.

black_pearl_gt

it really only surges at idle once you hit like 1500-2000 it stops

mattdel

clean out your Idle air control valve

can you maybe repost that link it didnt work for me and where is the iac vavle at (is it on the side of the tb?)

yeah, its the weird motor thing on the side of the throttle body. Make sure you reinstall it in the exact position you took it off (it will go on upside down). You may have a vacuum leak. Popping through the intake is either a valve (not likely) or ignition (possible but it would have to be extremely retarded) timing issue or a lean condition. A vacuum leak will create a lean condition. Make sure you pulled the SPOUT (spark output. This is a grey jumper plug that runs from a wire off the ignition module and is usually a pink wire) when you reset your timing. This disables the computers ability to control spark advance and will keep you at a base timing.

BTW, the shaft of the distributor may be worn out, did it feel like it would wobble in the housing?

black_pearl_gt

well i cleaned the iac valve today and it still surges any more ideas could i have damaged the distributor taking it apart.

black_pearl_gt

no it didnt feel wobbly but i didnt pull out the spout when i set the timing will that really make it act this way?

black_pearl_gt

anyone know?
