I'll chime in again and say that I have not had any issues since doing the TB cleaning on my coupe in May. Smooth sailing.

Exceptional Service?

So I had the dealer look at the throttle bodies. The tech told me he sprayed some throttle body cleaner into them. Car seemed to be more responsive and the idle was definitely better - around 6-700 RPMs. He said there was nothing in their database to indicate a problem with the idle or any problem with the throttle bodies. He also mentioned I shouldn't put too much stock in forums.

Got about a mile away and at the first stop before the freeway -

- car shuddered and dropped down to 400 RPMs. Guess I'm going to have to do this myself.

Sorry everyone for opening up an old post... Got a 2011 IPL this last weekend and have the same issue.. It definitely drops more with the AC on than when its off.. Was wondering if the dealer flashes was something you had to pay for? Probably I would guess.. Will try the TB cleaning too

When you say "idle bypass valve" would that be the Idle Air Control Valve? Can you take a pic and post it?

ummmm.....This guy made this one post over seven years ago and hasn't logged in since...not very likely that you'll get an answer, better idea is to start your own thread about your issue (with your own pictures) or bump a newer one
