Yes I have looked through throttle hang posts, and even found some of my replies in the search. I had bad throttle hang so I cleaned the IAC. This worked but neded to be cleaned a few months later. I finally replaced it and the throttle hang went away. Now only 2 months later and the throttle hang is back (you can take your foot off the gast like cruise control it is so bad). After pushing the clutch in it stays around 3-4K for a bit then drops. It is only there when the car (and the weather) is warm. Is there something else wrong? I have looked to make sure all the vacuum hoses are connected and they all look fine. I also made sure the throttle cable is not binding either. Anything else to check for?



What Octane are you using ?

I was having throttle hang until I downgraded octane (94 - 92).

Look up your manual and figure out what the real octane level is with r+m/2 cause I think octane differs from area to area.
