PLEASE HELP
My explorer has a strange idle problem sometime. When I start my explorer, everything runs fine, in park and in drive/reverse. The problem occurs when I start the car a second time.
Problem:
After the explorer is started and still in park, the rpm will lower to less than 500 rpm. This starts within seconds after ignition. The engine makes a high/low sound, as if not all pistons are firing (maybe?).
Once in drive, the idling returns to normal and drives fine.
When:
I park my explorer and turn it off to go inside (house, store, gas station). When I go to start the explorer again, the rough idle begins within 10-30 seconds. This idle problem will only occur if the car is turned off for a short period (2-5 minutes). I cannot leave my explorer running because someone could steal it.
Temporary Fix:
If I give the car gas while still in park, this raises the rpm and the strange sound goes away.
If I shift into drive, the sound goes away, but the low rpm remains.
PS:
I do know that the upper intake plenum is old and dried out. This is allowing more air into the engine.
