Driving today I got the dreaded "reduced engine power" P1516, a few times and it sux! I pulled over and shut if off, both times for less then a minute, and it was fine, but wth? Later on, as it was idling, I wiggled the hell out of the plugs and wiring coming off the throttle body, I went about a foot or so in and I couldn't get the reduced power to display. I've read a million times on here how that's usually the common issue. Anyone have any other ideas? It doesn't happen often but it's still annoying, and I don't want it to become a dangerous issue for us.
