well, check for any codes or anything first. then put a new fuel filter in it and see if that helps..it may be your injectors dirty or clogged or something. then check all the emissions nonsense make sure everything is working..

This truck has two o2 sensors upstream and two down. With the motor chugging at intermittent speeds. Which one should change first?

I am now throwing a code...Do not remember it. stated that # 3 cylinder is misfiring. Changed the plug and it will come back..Going to change the coil pack and put in a new spark plug, And new wires. i will post when it is done..I also put in 3/4 of a can of seafoam.. Seemed to clam it down a little bit.
