idle speed dropped or running rough at idle
Clean the inside of the throttle body with a dry rag. To my shocking surprise, it worked. I'm going to do this every couple years from now on.

RE: idle speed dropped or running rough at idle
Here's what mine's doing.....
When I'm coming to a stop or slowing down a lot to park, the cars rpms plummet to around 500 and then they leap to about 1500 and then plummet back to 500 and then leap to 1500.... Will cleaning my TB solve this problem? It's really annoying.

I notice when set at 750rpm in the tune, will drop to around 400 after a quick stop with A/C on and then jump back up to 750. Strange,but only happens with a certain tune (I have 3 different ones).

RE: idle speed dropped or running rough at idle
Haha! I think I found my problem! When I cleaned my cone filter the other week, I had also taken off the intake hose to look at the TB. Evidently I forgot to reattach the little hose that attaches to the intake hose because it was off when I checked it today.
I bought some MAF sensor cleaner and cleaned that, and I bought some TB cleaner and cleaned that. Neither was all that dirty that I could tell. There was a little black **** behind the butterfly, but just a surface residue.
I'm waiting a little to make sure all the cleaner evaporates before I start it up again.
What is that little hose I forgot to attach? Could that have caused my lunging idle problem?
