car bogging issues
hey guys,
as some of you may know my car has been having some issues. after my car gets to around operating temperature and when i come to stops or push the clutch in. my RPM dives down and dips really low 300-500 rpm. sometimes it even shuts off. Vince at Trifecta said he didnt see anything wrong in the datalog. Also what i notice is my vacuum bouncing around 20-15 after car is at operating temp. Every once in a while i also get a nasty valve train noise after starting car when its already warm but that noise isnt happening as much as it used to. Let me know what you guys think, extremely annoying to deal with
