skipps and sputters when cold
the engine is skipping and sputtering when its cold and try to accelerate, after driving for about 2-3 miles and it develops some heat this condition goes away. it appears, to me, to be temperature related. it is worse in the morning after the truck has sat over night. it happens again after I leave work, but seems to clear up faster and not be as bad.
any ideas what to look for? I have replaced both fuel filters and the air filter. I also cleaned the MAF sensor.
to me, it feels like its starving for fuel when it happens.
maybe it needs a tune up (new spark plugs and wires)

I hooked the scan tool this morning before I started the truck, outside temp was roughly 65 (F) degrees. engine coolant temp was 68 degrees and Intake air temp was 70 degrees, but the Engine Oil Temp was reading 105 degrees ! is that possible, or is there a problem?
FICM voltage is sitting at 49v, which seems to be normal.
My engine oil is clean, not over full and doesn't smell like fuel.

Worn injector O-rings usually
or a cracked head but this is not common
this was an issue for me
and when winter came it got worse it was around 60,000miles on truck they would only leak untill warm then they would seal
in the end I would make a quart of oil every 2 weeks or so
since I fixed this my bell housing dried up and so did the bed plate seal
truck runs Great at startup harsh cold tranney shift gone
But just keep in mind cuz your FICM volts was good doesnt mean its running 100%

but did notice the Blue rotella T-6 for 20.00 a gallon
mobil1 synthetic was 30.00 a gallon at oreilys
IDK hate to change back and forth between oils
