Tricking the ECU to Relearn AF map

[kustom play]

well looks like good news

so i disconnected the battery for about 3 hours

came back and hooked it up started it up, it oscillated a bit then came down to normal

so i waited about 5 mins after that, then reved it up for about 3 more mins

after a while of reving the car started oscillating again so i stopped and let it settle

then i reved it back up for another 2 more mins and then went for a drive

i drove about 110 miles today with no CEL or no problems

looks like im in the clear

i hope it fixes the problem

I wish you all the luck in world and I hope this solves your problems. For me, after 3 days, the oscillation keeps getting worse and I've gotten several CELs. The chip swap is next on my to-do list.

Do you still get the high cold idle with the tC throttle body?
