New Life for a truck passed its prime

[keniff]

timing gear lined dot to dot with the crank gear for the timing chain? if its so far off itd run like poo. uh o2s arent working correctly. uh did you try u plugging MAF to see if thats the problem? are you getting a studder ou of it with a back fire or itll barely throttle up with light back fires?

i understand you saying it wont stay running but by that whats it actually doing? i sure wish you had the scanner to see exactly what its giving you an maybe someone with more knowledge can help.

oh pull a plug an see if they are geting burnt up, an recheck the grounds. sounds dumb but could have a loose wire, pinched wire.

I made sure to line up the timing gear dot to dot and I think if I hadnt it wouldnt even run this well. Its just rich as hell. Not sure whats goin on with the O2s but they are brand new Bosch O2 sensors. We put mufflers on it so the O2s being so close to the end of the header shouldnt be a problem anymore. I first started the truck without the MAF but it didnt seem to make a difference when I put a brand new MAF on.

It doesnt really studder it just doesnt want to start and doesnt want to idle and wont handle a load very well. Also it doesnt want to idle after I rev it. Usually it surges and dies after I rev it. BUT, thats one of the things that got better last night when I was driving it around the block. I know the surging usually points to a vacuum leak but Ive checked for vacuum leaks and doesnt even seem like a vacuum leak type of surge. It does backfire a bit now that mufflers are on it.

Ill take a vid of it tonight to let yall see everything its doing. Also, my friend is bringing his scanner back over so we will be able to see what the sensors see again. I kinda thought with the info I posted on here from the scanner that some of the experts on here could tell me whats going on or atleast tell me what sensor is way off but Ive gotten no help. 93 views of my thread in the tuning section and only one reply.

Ill pull plug and check the ground tonight but I dont have to pull a plug to know that its stupid rich. I can tell by the smell and smoke. My friend Ed who is a service manager at a local GM service center said after hearing of the fuel trims that its the most rich that the computer can compensate for.
