It's not missing currently. The weirdest thing is it's basically just idling about 200 rpms below what it would do normally. The intermittently it will suddenly drop 100 rpm or so and come back.

A dirty throttle-body butterfly will cause that also..... So will the Idle Air Control (IAC).

You might try youtube and search for "idle problems" or such as that.


Today's vehicles are harder to diagnose because the systems are more intricate.....even though the basics are still the same: fuel, air, and spark. It could be anything from a bad plug wire to a bad injector to the fuel pressure regulator.


Here is a link with some things to things to look for.

all fuel is exactly the same until it hits the trucks,  so unless your getting bad fuel( water or old)  that plays no roll,
