Hello, I have repaired exceeding 30000 vehicles in my career and I obsession to ask you questions back I am not there in person to collect facts, data, or to exam your vehicle. I may ask you to do its stuff psychotherapy in my stead. If study is needed and you would rather not put on an act testing, I can have the funds for my best advice, Fuel pressure?
I started the car occurring this morning, it starts up and runs at 1750 and within a minute or for that reason climbs greater than 2500.. It is direction smooth though, just quirk unconventional than it should be. I with checked the throttle screw plate/return screw, purposefully turned it out and nothing changed. put it encourage to exactly where it was. No vacuum leak sounds and all friends verified. I mood fine about them as I've been in there a bunch of times..
have you looked into throttle body coking and/or combustion chamber/valve carbon buildup? are you stirring to date on every maintenance; spark plugs fuel filter pcv vlave etc? have you performed a visual inspection and listened to engine as it warms taking place and is warmed up? oftentimes in engine action many factors may cause the thesame symptom(s)
