So I've been going through trying to adjust my idle...but i can't make it go down... Less i set my rev limit on the pfc to under it.
simplified sequential(idled perfect before simplified sequential)
took everything off cept the icv
mid pipe and cat back
It idles smooth, can rev higher no problem... Just can't get the idle down
Did air bleed screw. Haven't done the tps adjustment cause i can get to the screw, have to take the tb off i suppose. voltage is slightly high but would it make it idle that much higher? Also...nothings really touched the tps but would it go outta wack just from taking the throttle and uim off..
Yes. After warmup your VTA2 voltage (narrow range sensor used for idle) should be 1.00 volts or less. You can actually physically rotate the fast idle cam with your finger and observe TPS voltage differences.
Also, if you eliminated the TB coolant hose you must remove the fast idle cam from the TB or use a zip tie to rotate it away. Otherwise you will have a high idle and high TPS voltage.
