Check the hose clips for tightness and examine the trunking for any cracks or splits and along with all the vacuum system, the small bore pipes and fittings for cracks and missing parts. The best habit to find a leak is to have the engine presidency and hot and after that spray can lighter gas /propane or brake cleaner all but each joint in turn. If the engine rev s occurring you ve found your leak.
I did re-check them tho. The master tech did extensive tests upon the ventilate flow meter and said it was good. later I unplug it and rule the motor, the car runs rough and at 850ish. I can single-handedly guess that my new rebuilt ecu has an issue, or the tps needs to be re-adjusted, or someway my maf has died in the midst of every this. I don't think the tps has that much manage in the every other of rpm though? I think it isolated adjusts it all but 1k..
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 in the works and is warmed up? oftentimes in engine take steps many factors may cause the same symptom(s)
