You clean the maf or do a tune up lately?
Wrong plugs can cause problems.
Cleaned maf two weeks ago.
Tune up last year.

Pump and sock brand new.

My TPS signal wire is reading 3.6 volts at WOT. Seems low but i hear some models peak at 3.5. Is this pos supposed to read 5 volts wot?
A little backstory that might help.....I been having rough starts that last between 5 to 20 seconds.It would idle like a tractor then smooth out. I also get a bit of white smoke on startups that fade once it is warmed up. My mileage has been sucking as welI. I replaced the Engine Temp Sensor, fuel filter, PCV valve, coil packs, cleaned MAF and all TB components. Plugs and wires looked fine.
Then sometime about a month ago it started jerking and cutting out under load on the highway or when hauling heavy shit. I thought pump was going and then this shit started two days ago which prompted the pump replacement.
