I have a 99 Tacoma 4 cylinder with about 62,000 miles on it. When I come to a stop the idle will jump up briefly and then come back down to normal (about 1000rpm). It does NOT surge over and over again, rather just jumps up once.
There are no other idleing issues, other than this everything is great.
I removed the throttle body and IAC and cleaned them all out. Didnt help.
