2.9 stalling while driving!

[mtingen21]

I have a 1992 ford ranger v6 2.9, and I am having issues with it stalling after warming up. I have replaced the ignition coil, fuel pump, fuel pump relay, tfi module, and the pick up coil. Any suggestions??

Did you check the IAC valve? If it is working the motor should die if you unplug it while its running.

I had an issue with my MAF that caused my truck to die on me randomly. Sometime the MAF is the issue try cleaning it

Took the IAC off and clean it, haven't checked the MAF sensor yet.

WOW, I guess them it is a Speed Density that make the problem a little harder. Remember Speed Density uses engine vacum as its way of calcuating the engine processes. give me some time I will look into this

IAC's on the 2.9's are notorious for this.
