Idle Speed too high
Hi,
My D (99 5.9l) has suddenly developed a problem with the idle speed, espeically on start up in the morning from cold.
The speed is too high(1200 rpm +)...I suspect a problem with the Idle Position Sensor, which I assume is similar to the TPS that I also recently replaced to stop the "blipping" of the engine speed whilst on cruise control...Anybody agree..??

RE: Idle Speed too high
I'd suggest pulling the TB and cleaning the whole thing. plus while your in there take a peak down the intake manifold and see if there is any oil pooling on the bottom. if so, this would indicate a leaky plenum gasket. easy fix if you can wrench. common problem with the magnum motors.
