Starts then dies...

[daffy]

I've got a 2000 EB, and now that the cooler months are settling in, a problem is re-occuring for me.

I'll (cold) start and drive the truck just fine. When I stop (turn off) for a short amount of time (5-15 minutes), and go to re-start, the truck will start, run up to 1800RPM, down to 14-1500, then die, maybe 2x, then it will bounce down to 1-200 (feels real rough like it's going to die) then recover and be fine. I've been reading threads, and haven't seen anything similar, but I'm thinking of trying the "seafoam through the PCV" treatment.

Any thoughts?

Thanks!

i think this is an iac problem? gets stuck

This could related to a number of things such as the fuel filter, IAC, MAF, TB, ACTS, ECTS. Start by cleaning out the IAC, MAF, and TB.

sounds like one of the air sensors or maybe a sticking injector but start with the sensors.

Thats a typical IAC problem for the 4.6 and 5.4 and the V10. YOu can tap it with a hammer or shimmy the gas pedal to keep it going....Many people try to clean it, but thats never a permanent fix. Its just two 8mm bolts, and about $65 most of the time.

I too vote for an IAC issue.

Good luck .....
