ive heard of this on other del sols but how do you fix it??????

please help..any info

that's because of idle set to high, the IAC valve, or a vacuum leak. you need to take out the tps sensor plug and adjust the rpms until you get to a normal idle, then recconect it, stop the engine and reset the ecu.

i did that already

i think it may be a vaccum leak but someone said something about the idle air control valve????

You haven't by any chance advanced your timing recently, have you?

Just checking, cuz a buddy of mine a while back rotated his distributor cap a little too far and ran into idle problems, we all mocked him mercilessly until he changed it back.

can be adjusted but i don't know how. you shoud hahe some screws to remove a cap and roate the internals of the valve until it does not do it anymore

?????????
i already pulled the valve off once
are you referring to the black cap piece on that top of it????

well on mine it is a aluminum cap, and i think yours might be different since you said a black cap
