Won't rev above 4000 when stopped?
Recently did an oil change on my D3 S8 and have been going through some other issues but everything seems to be running OK so far. Last thing I tracked down was a "gross evap leak" which was a bad gas cap seal, typical. Right now it has no CELs and everything runs great, but for some reason when stopped in park or neutral, it refuses to rev above 4000rpm. Before the oil change I could do that just fine but ever since the oil change, it refuses to go above 4000rpm. Running and driving is just fine, no CELs at all, just won't rev above 4000 when stopped. Anything I should be looking for?
