So just recently my car has decided to idle like a V8...runs and drives fine but every once in a whilw when i stop at a stop light or whatever the idle surges like its under load. It does thisfor a minute or so sometimes to the point of stalling. Any ideas?

 

Ok first what motor . . . any check engine lights on . . . any work done to it recently . . and how does a v8 idle can u be more descriptive

 

all my v8s idle nice with the exception of the nice lope from the cam. so more descriptive

Lol sorry...havent posted in a while and forgot to be descriptive...B16b with a bunch of goodies cams springs retainers pnp so on and so on tuned by chrch...car has ran fine no changes in the last several months except oil change. as for description....in gone in 60 seconds the movie....after he steals the mustang and brakes the mirror off and the car starts to die....just like that. The RPM's bog really low almost to the point of stalling and then it recovers itself, it does this a few times while waiting at a stop light. If i give her some gas shes ok, and generally fix the problem. mind you it only does this every once in a while, generally right after the car has hit operating temps then it will be fine the next time i stop.

 

vacuum leak?

 

no, try cleaning the iac valve out. no codes?

 

Well my V8 idles smoothly, so I'd say you don't have a problem.

No codes, cleaned iac about a year ago could it really need it again?

This is almost like parasidic drag on the engine, kind of like when you roll up the power window and the idle dips...only i have no accesories on at the time....it will also do it when i have the steering wheel cranked...(light bulb moment)...could it be the power steering pump some how causing this effect even with the wheels pointing straight?
