hot idle

Howdy Pelies,

All is well down here in Texas except for a small idle problem. It seems after she warms up a bunch, something changes. Normally when I am driving, and I let off of the throttle, it goes full lean. Lately, when I "let off" it seems as if she's getting un-wanted fuel. My air/fuel mixture gauge shows "blips", my idle hangs, and she is running rich at idle. ALL only when she gets to operating temp.

Any thoughts?

Thanks,

Rick

Adjust your TPS so that you hear a click from it every time the throttle is fully closed. (won't hear it from pass comp)

Ok, I hear a "click". However when it clicks it doesn't always cut the idle. I am going to rebuild TPS. I will report back.
