I have a 05 dmax with the 5 speed allison, a few weeks ago I started getting a p0500 code pop up with my cel light. If I erase it,it drives fine bit feels like theres no converter lock up. Shut off truck and turn truck back on and start driving it gets to about 1800rpm and jerks like I put the pedal down half way then it drives normal. Replaced the speed sensor 3 times none of them helped. One wire appeared to be bad (purple with white stripe) and I replaced that wire. Still having the problem. Speedo seems to work just fine as well. This is the only code I have , no abs lights or anything else. What can be my problem?? I'm stumped. Any help is appreciated. Thanks! Btw I do have efi live tuning and it is currently tuned to the correct size tires that I have.
