I have the crazy p0171 system too lean light on but, I have changed the maf and both o2 sensor and the light is still on even when I clear the code out with a hand held computer. I just took it to my local toyota dealership and they hooked it up and told me 4 cylinder fire and 2 don't. The dealership tech told me to take it home and run fuel injector cleaner thought it and that did not work either. I need a dealership in the mississippi delta or memphis,tn area or someone that could fix my truck!!! HELP!!!!!!!!!!!!!!!!!!!!!!!!!


P.S. When the truck gets hot it backfires and misses and dies!!!!!!!!!!!

Could be carbon build up on the cylinder walls. Carbon gets hot, ignites the fuel mix when it's not supposed to... Here's a quick link, better ones out there, but you get the idea.
