Hi! I haven't posted here in a while, but anyone experiencing the same problem that I do? Anyway, whenever I drive my car and stop on traffic with the AC on , my car's RPM dips around 400-500 then come backs up(acting that it will like to stall). What do you guys think? Bad IAC? or my throttle bodies are just dirty?

I had this happen to one of my previous vehicles. Cleaning the TB always fixed it - so I'd start there.

Im thinking the TBs gets more dirty because of the aftermarket intakes?( I have JWT)

Same problem here. I took it into the dealer and they reprogrammed my ECU saying there was a TSB for it. Still the same problem... I'm gonna ask them to clean the TB, if not I'll use the DIY on here.

Dp you have aftermarket intakes as well ? How many miles in you car?

Dirty TB's are not caused by intakes or their filters but from the oil vapor from the crankcase covering the back of the TB valve.

^whs, what some AM intakes do is that they require for you to remove the breather elements on both ends which causes more vapor to enter the TB and get dirtier quicker.

Hey this is happening to me right now i just bought the car 2 months ago and i have same issue and its more noticeable when the AC is on. When i stop the rpms drop and the car shakes feels like its gonna turn off. hopefully its nothing bad. Anyone know any fixes??

Do you have after market intake?

I've had this problem for a couple years; just an annoyance really as idle would flutter and then come back up. Finally I had the dealer do a throttle body/fuel induction service last week and problem is gone!

^ yup like Q8y said just do the TB cleaning and you'll be good for another 15-20k miles
