So, at 160k miles, having my first real problem. The car runs great, can drive it for hours with no problems. But if the engine has been on for awhile, if you shut it off (like when gassing up), then re-start, it goes into engine malfunction reduced power mode. Throwing code P1290. I cant believe its anything serious because it will run great all day if not shut off, and also if you wait awhile to restart, its fine. But if you shut it down, and need to restart and go, stuck in limp mode. Bad engine or coolant sensor? Wastegate? I dont think I would do a very expensive dealer repair at this point...And it wont pass inspection like this..Thoughts?
