Driving around, I came to a light, car started bogging down, idling very low 100-300rpms, almost stalled. Kept fluctuating rpms until it finally stalled. I noticed prior to this, the rpms were a tad high idling In neutral, coasting to a stop. Than this happened. Where to start?

 

Forgot to mention, 01' with F22. No CEL either.

 

Start with the MAP.
Whack it.
Really.
Search for MAP whack in the FAQ.

 

I started it, ran good. Let it warm up to 3-bars and it still hasn't bogged down. I am going to clean the IAC anyway.

 

Cleaned the IAC really well, it has been idling much smoother and so on... BUT, it started bogging down again but this time it wasn't as severe as it was before. What else to check? MAP?

 

Maybe it's just heat soak?

Hot weather + A/C on = occasional bogging

 

No, its only done this at night actually. Bogging as in its idling 100-200 rpms and stalling too :/

 

try Some Throttle Body Cleaner... And Check Injectors... I KNow They Dont Fail Often But They Do Fail...Also It Could Just Be Your Fuel filter.. I Kno If You Have Heavy Sediment It Clogs the FilteR Partially Then Goes Away

 

What gets me, is that so far its only been doing this at night..
