They told me it was spot on and that my rear control arms were leaking oil.... but they have conZult and let me in the garage while they checked it.
Once you get timing set it helps to mark its position for future reference. The Idle is pretty easy to set the hardest part is getting the connector off and the AFR is controlled via ECU and should be correct if everything else is functioning properly. A lean mixture would cause it to run warmer u can run o2 diagnostic on the ecu for peace of mind. Stock or aftermarket temp gauge? What are your plugs gapped to?
