If the timing chain skipped wouldnt the timing be way off? its dead on but the truck ran much better when it was off a little haha. TPS has been checked by PO but i will do it again just in case...im leaning towards my valves being way off or maybe a plugged EGR......lol never thought id say it but i kinda miss my 3vze right now!!! If its none of those, theres a guy in town they call Toyota Moses, I hear he can diagnose a problem just by the sound of the motor a mile away! and this truck will be taking a trip to him, im just too cheap to give up yet

 

oh and ive never plugged it in. but its on the list...
