So awhile back i posted on an issue i was having with high idle
Short background.
huge nitrous backfire ( my fault ) after that the car would not drop idle below 25-3k.
Went trough all kinds of stuff, replace upper and lower intake gasket, replaced IAC, replaced TPS and replace mass. even cut the #3 pin on the EEC.
After all that i was able to bring the rpms down to about 1800 at idle, but once i drove rpms would jump back to 2200 sitting at a red light and hang about 2500 between shifts.
So tonight i decided to give it one more shot, pulled the throttle body and gave it a good cleaning put it back on and same idle issue. i then noticed a HUGE gap where the plate on the butterfly wouldn't close flush. swapped it out with a fox and now it idles perfect and no hanging.
So only thing i can think of is, the backfire was so strong it bent the plate.
Now maybe its supposed to have a little of a bend to it, but all i know is swapping it out fixed the issue.
