2000 bone stock S/cab, 4.0 ohv with a 5 spd. auto., 77K miles
At times, after a long period of deceleration the engine will run rough, barely idle @ 400-500 rpm, like it's loading up. Bringing up the revs will clear it up.
The MIL light does not come on, indeed my code reader indicates no problem codes at all stored in the ECU.
Plugs and plug wires are new (Motorcraft platinums),both the throttle body and IAC are clean. Yes, the air filter is clean, fuel filter was replaced 5K ago.
Haven't checked the MAF yet, suspect the problem may be with it, and/or O2 sensor(s), thing is no codes are being displayed.
And..., this problem is intermittent
Anyone have a clue?
