97 3.9 dakota when it's cold outside and I start my truck it'll start right up but idle down til it quits . Start it again and it will idle.. Go down the road and it misses bad until it warms up. After it...

Here are the most common causes of idle surge, rough idle esp when cold and stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

Engine dies at all speeds

I suspect an IAC (Idle Air Control) valve fault, or it could just be that the idle speed requires adjustment. Have you had a flat battery or a battery replacement recently? This can cause the computer to loose its learned idle settings and bring up these sort of issues. The idle should relearn itself in this situation after a few days, but sometimes requires resetting properly.
A competent auto technician should be able to diagnose and rectify a fault like this quickly, the idle systems are not too complicated on these vehicles.

Starts, but put it in gear, it goes dead. will idle.

1. Had mechanic check timing again. Belt off a couple degrees. Should fix problem.
2. Don't know. this is my son-in-laws car.
3. No.
4. I think valves were bent due to timing belt breaking and son-in-law trying to start car when it went dead.
5. Will do this if timing belt reset don't work.
Thanks for your reply.
