01 5.2 Manual Idles up when pressing the clutch
Not sure whats going on here. The problem started yesterday, if i'm going more than 5 mph and i push in the clutch or put it in neutral it idles up to 1500rpm. Normal idle for my truck is around 650-700. Even if I'm riding and running at about 1100rpm and go to shift it will try to idle up to 1500(and on the rare occasion 2000), but if i am slowing down and get below 5mph it idles back down to 700. I've replaced the tps so far, but was just wondering if anyone else has had this problem and found a solution before i go replacing the iac valve or anything else.
Edit - 2wd if it makes a difference

the IAC (mostly) and the TPS (some) interact to control the idle. the IAC motor moves a little plunger in/out of the well on the back of the throttle body to control the amount of air bypassing the closed throttle plate. its the most likely culprit in idle problems. replace it but if it doesn't fix the problem, keep the old one as a spare. same with tps. they come in handy in the future.

heat works good still and do not have cruise. i haven't checked the intake gasket, and i dont remember if i reset the pcm, i'll have to do that before i leave for work today. Also, no codes. it idles up and holds there until i get down to 4 mph then it idles down to 650-700 which is normal for my truck. i'll post if resetting the pcm works after work tonight. if anyone else can think of anything please post.
