Hesitation

Got the truck running pretty much back to normal except for an occasional bogging under load and sometimes at idle. Power is there but it disappears randomly. Any ideas as to what this could be, there is no cel and I have replaced every sensor.

so you say you did replace it? I beleive that one is not adjustable, but you can check it. Just use a multimeter and check the resistance as the move the throttle plate slowly, any jumps or drops in the numbers means it has a bad spot. Also you can try and clean the throttle plate to be sure its clean. Also what octane fuel are you using? I beleive 87 is recomended, if you go higher it can cause hesitation.

I am using 87, I tested it before and after I replaced it. It is doing right now. Also the throttle plate has been cleaned. CEL just thrown, going to get it checked tonite.

You should try checking the wires and coil packs also, maybe one has a slit or crack, good luck, hope you find the problem...
