Hello,

I have a 2001 escape v6, when I press the gas pedal it accelerate fine but then the rpm's are slow coming back down to normal. I cleaned the throttle body but still does the same. Even when in "park" I rev (accelerate) the engine and goes up fine but then it kind of stay high for a fraction and start going back to normal idle slowly.

I hope Im explaining my self right. Any ideas? Could it be the IAC?

??? Anyone? So I replaced the ICA, cleaned the throttle body and Maf sensor and still.... again, when I rev up the engine it's really slow to come back to normal idle... anyone have any idea what could be?

Ok, So I just did something else... when I disconnect the plug from the IAC it rev perfect... so WTH? But the IAC is new, I connect the plug and start doing the same thing. ????

Actually with the IAC disconnected the engine should almost stall and turn ON the CEL also. Sounds like the IAC is being commanded by the PCM to do what it's doing.

I know, Thats what I read, but when you disconnect it actually rev perfect...weird....It actually idle good but when you rev the engine its really slow to come back down to normal idle... oh man, I have no idea what else to try..

How long are we talking here? Extra seconds, or over a minute to get back to idle? Mine has always come back down slowly, especially before the engine has warmed up.
