How worried should I be? Ran to get lunch today. Pulled out from side road, 3/4 acceleration to 65, leveled off and slowed to a stop at a redlight 1 mile up. Stopped at the redlight, suddenly engine idle drops to 400ish and shakes badly. I put it in neutral, it idles slightly better but is def rough and not right, rev it up to 1k and it feels smooth but not right.
Baby it on the drive home, it feels as if it is in limp mode. No check-engine light. I stop halfway home, turn the truck off, then back on, and it idles and drives like normal.
Scanned DTC's once I got home, and found P0018 and P0021 as history codes. Cleared them, test drive - everything seems fine.
So....whats the chances of just an intergalactic glitch, vs something more major about to rear its ugly head?
