Idle Dips then Recovers....
Whenever i come to a stop light or i am otherwise standing still and i rev the car slightly and let go, the idle goes WAY down then slowly bounces back up to 750rpms.
and also if i tap the pedal once or twice while idling the car will sputter then stall.
although when i am crusing down the highway and do the same things, the idle never drops that low. the symptoms tend to be more prevalent when the engine is hot and has been running for awhile.

Any check engine light coming on? Had that problem recently and it was a bad coolant temp sensor. It was throwing a code which made it easier to diagnose. Also, the problem went away once the car warmed up. With a bad sensor, the ECU screws with the fuel mix if it gets a bad temp reading = idle is all over and car wants to die and then almost impossible to start back up once it stalls. I also heard that a misadjusted TPC can cause this.

i changed the plugs and it seemed to help slightly but that just could have been wishful thinking.
the check engine light isnt on.
the clutch switch would make sense but it does it the same reguardless of the cluch being in or out. does that make a difference?
could someone better explain the dash pot, diverter valve, and tps for being posible causes?

Not to thread jack but I think I have the same problem? Its something small that I just ignore but a fix for it would be cool. Is it like when you ever so slightly tap the gas then immediatly let go the car dies or comes VERY close to dieing? Yet if you give it a good rev it has no problems?

if i rev at all when im standing still, the rpms will fall to almost dying, but when the car is moving its perfectly fine.

I am having the same problem as to where i will tap the throttle rapidly, the car will stall itself. No matter what temp the car is at.
Was told it was the TPS and im leaning towards that because it was the last thing that was touched before this problem.
I checked clutch switch and its not that. Everytime the car stalls, it starts up right away.
