95 tahoe idle up and down
hi. I have a 1995 tahoe 106,000 miles on it. it recently started acting up i. It runs fine when its cold outside, but when it warms up it runs rough stalls and idles up and down about 800 rpms. almost to stall and then back up to normal. I replaced the throttle control sensor, but the problem has persisted any help would be greatly appreciated. thanks, chuck

changed out the iac, and map sensor. still no luck. go out in the morning when its cool out runs good. after work 55 degrees out starts the up and down idle. any ideas? thanks chuck
