Mine just started doing this. Had a friend set the timing with a snap-on timing gun that shows rpm's and timing, he set timing running just straight headers no exhaust. I put the exhaust back on with cat converter & muffler , this seems like when the dieseling started. Also its sluggish in 2nd gear only.
