I have been having bouncing idle trouble for the past weeks, i have cleaned and replaced a lot of parts ( IACV,PCV, and cleaned) on the original throttle body, i had a mechanic look at it and he told me to reset ecu and replace throttle body, i reset the ecu by taking away power and waiting 15min. that seemed to help with bouncing but idle was at x1.5 high and after rev it would dip down.so i went ahead and replaced the throttle body with one from Pick & Pulls. now im having bouncing idle when engine starts.
Could it just be the ecu learning the new throttle sensors?
any ideas would help out alot, thanks.



PS coolant seen on video is from me zoning out and lightly removing tube from iacv valve.

 

That's a famous vacuum leak my friend. Check all your hoses to the throttle body and intake. There is a leak. If you can't find it. Use some smoke and see where it goes.
