Once the truck gets to operating temperature it hesitates and sometimes stalls, the stalling happens mostly in reverse and it only happens in drive if you hit a certain spot in the gas pedal when taking off. The truck starts right back up every time. Once you get past the little hesitation she is smooth as silk. The TPS is new, the IAC valve is new and the MAP sensor is new. The temperature gauge doesn't work the switch might be bad but I think the truck would run like crap all the time if that were the case... It's easy on gas, It doesn't smoke at all, great acceleration, it's just that one spot as soon as I put the weight of my foot on the gas pedal. It's all I've got to drive so I've gotten pretty good a missing that spot, but driving it is only going to make things worse. I read in another forum that the transmission fluid/filter could have something to do with it (something about the filter falling off and laying in the pan?). I know my way around these trucks pretty well and this is the only one if the 12 I have owned that stumped me and im losing sleep over it any input or advice would be greatly appreciated!

Have you checked to see what the computer knows? (Fault Codes)

We can help you MUCH more if we can review all the truck's details & history in your signature, as this caption explains:


(phone app link)Why? When (time/miles)? What was wrong with EACH of the original parts? Did each new one pass the same test that the original failed? What (brand/PN/source) is each replacement?The gauges have nothing to do with engine management. The EEC uses the ACT & ECT to read temperature, and each one needs to be tested, as this caption explains:
