 Subject: Revs drop in reverse
IP: Logged
Message:
Every once in a while the revs drop way down and the truck sometimes dies when I shift into reverse.
Also if I only drive a short distance and I shut it off for a few minutes the revs are very low for a few seconds when I restart.
This second problem only happens when the engine is still cold.
Any ideas guys ?? Much appreciated.
It's an 01..3.9..auto..20,000 miles

I would try cleaning the IAC Solenoid
Maintenance: Cleaning the IAC Solenoid
This is recommended at every Tune-Up to prevent excess carbon buildup on the IAC plunger. In some cases, you'll notice a slightly erratic idle quality. This is the first step in taking care of that problem. IAC = Intake Air Control (Solenoid).
1. Remove the Air Hat from the Throttle Body
2. Disconnect the sensor harness from the IAC Solenoid (Rear of Throttle Body)
3. Remove the two Torx-25 Screws
4. Remove the IAC Solenoid (Be careful not to lose the rubber O-Ring)
5. Spray some Carb/TB Cleaner in the IAC port on the Throttle Body and let it sit.
6. Spray some Carb/TB Cleaner on the tip of the IAC Solenoid and wipe clean (Do NOT forcefully twist or push the plunger - You will damage the Solenoid. Wipe very gently.)
7. Spray a little bit more Carb/TB Cleaner in the IAC port on the Throttle Body and wipe clean with a thin/lint-free rag
8. Reinstall the IAC Solenoid (Make sure you don't lose the rubber gasket on the solenoid)
9. Reinstall the sensor connector and airhat
10. Start the engine and let idle for about 1 minute.
