Thanks, should I start with spraying some starting fluid around idling cold motor and if no increase in revs, go to fuel filter? Would dirty MAF be a possible problem. When he 1st had this issue, the air filter was really dirty. We replaced but didn’t fix problem. Maybe that would do the opposite of running lean.
Thank you.
