Random drastic rpm drop at idle

Asked by Apr 19, 2018 at 05:58 PM about the 1998 Dodge Ram 1500

Question type: Maintenance & Repair

98 Dodge ram 1500 5.9.
Recently started having a pretty predictable idle drop to
almost a stall. Exhausted many replacement parts idle air
control throttle position sensor check vacuum leaks period to
no avail. Wonder if anybody else has had a similar problem
and can throw some advice at me I'm at my wit's end. When
is not acting up like the above said the truck runs great I've
only got a couple thousand miles left till 300,000 on the
engine.

1 Answer

Bump.... After I start it up the problem will start within 5-10 min of driving. I've figured out if I give it full throttle a time or two it will not act up again till I turn the engine off and start again.
