I need help!! rough idle!!

[95grntsi]

Well this all started the other night when i snapped my throttle cable the other night. no problem threw it on the trailor, got it home and ordered a new cable. well, while i was waiting for the new cable i decided to replace the turbo gaskets so i had the manifold, turbo, o2 housing all off the car. while that was off i decided to clean up the engine bay a little bit. so i covered up all the electrical sensors and exhuast ports on the head and used some degreaser to clean things up a bit. after hosing it down it really looks great!!! so the next day the cable arrives, I put everything back together, change the oil, flush coolant system and add new antifreeze. well i went to start it up and it started just fine but idled at between 550 and 650 rpms. so i revved it a little bit and it wont go past 1500 rpms. so i replaced the plugs, wires, and blew out the sensors to ensure they were dry. started it up again and same idle and no go over 1500 rpms. i tried adjusting the biss screw and that did nothing. today i pulled the ecu to see if the chip had fallen out of the socket but that was fine. also checked the timing and that was perfect. i dont know what else to check? the car idled fine after i snapped the cable.... someone help me please!!!!


sorry for the novel......

Check your throtle posioning sensor. It might be bad. Is your check engine light on? if so you could take it to autozone or advanced, they do free diagnostic checks.
