P0601 engine putts, pops when accelerating
about 6 mnths ago my check engine light came on reading P0601, but until about 1 mnth ago everything ran fine. It started with a little putter in the engine about once a week, then is gradually got worse. It almost feels like the trans is trying to shift just for a fraction of a second, but no change in speed or rpm. It usually gets alot worse when the engine is hot, the air conditioner is on, and I am accelerating. Then about 2 weeks ago it started making a small popping noise that sounds like its coming from under the hood. I dont think its a backfire cuz its not real loud and its definitely coming from the front of the truck, but it only does the pop when the putting is going on. Then to make things even more confusing, some days, for days at a time, it runs absolutely perfect. If anyone can give any advice I would greatly appriciate it!

First of all, sorry i fell off the face of the earth. Ive got a 1 month old son, been a little busy! Its a '99 5.9L 4x4. How do you RESET/REFLASH the PCM? Ive heard from others on the forum that if the PCM is bad, You'll know it, thetruck will not run!

Dont know if thats the same thing.
