This all started at my last oil change about 2-3 weeks I have been traveling and not driving much thus the delay in my post.
There are about 131k miles on the truck. I noticed when I cruise on the freeway around 70 I get a sputter every now and then. It's not consistent and it doesn't happen when I am accelerating. Yesterday when I started the truck it was about 55F outside and the truck started very rough with some white smoke for about 15-20 seconds. This morning I had the same issue starting at around 35F. But, this morning was the first time I have driven the truck in cooler weather since my oil change (its been warm here in ATL). I drove 25+ miles to work and the temp gauge never went above L. I am using a ScanGuage 2 to monitor coolant temp and oil temp and neither went above 130F for the entire trip.
Does this sound like I have an injector beginning to fail or did somebody put the wrong weight oil in my truck or am I way off base?
Thanks for any help!
