Hi guys, first post on this platform. Purchased my first GMC truck, hell my first truck ever, and loving this rig.
Elevation trim with the 5. 3 V8 engine.
Currently sitting at around 1180 miles. I changed the oil at 1050 miles with mobile 1 0w20 (8qts.)
Today while highway cruising, I Noticed the engine icon started to flash for maybe 10-20 seconds on /off and then it went away.
From what I've gathered could this be a cylinder misfire this early on?
I will pull codes tomorrow if any but again, this happened so quick and it never came back.
I did not feel any loss of power or anything unusual.
Oil level is good also... Should I have the dealer check it out?
Any others with similar scenario?
