Ive been having idle issues after driving for a little while the idle will be high.. when in drive coming to a stop it is at around 1500 and when in park or neutral it jumps to 2000-3000. Ive been beating myself up trying to figure out the issue.. replaced tps, IAC, cleaned MAF sensor. I just remembered that when i cleaned the throttle body i removed the screen... i figured.. wtf why have it there. Now that i have read a little bit it seems it has caused some issues with some cars when it is removed. I know it can cause a rough idle, but can my idle is smooth.. just extremely high.. think this is the culprit?
