Check the hose clips for tightness and examine the trunking for any cracks or splits and after that every the vacuum system, the little bore pipes and fittings for cracks and missing parts. The best way to locate a leak is to have the engine direction and warm and then spray can lighter gas /propane or brake cleaner in this area each joint in turn. If the engine rev s happening you ve found your leak.
I did re-check them tho. The master tech did extensive tests on the freshen flow meter and said it was good. considering I unplug it and control the motor, the car runs coarse and at 850ish. I can solitary guess that my further rebuilt ecu has an issue, or the tps needs to be re-adjusted, or somehow my maf has died in the midst of all this. I don't think the tps has that much run in the exchange of rpm though? I think it abandoned adjusts it around 1k..
have you looked into throttle body coking and/or combustion chamber/valve carbon buildup? are you in the works to date on all maintenance; spark plugs fuel filter pcv vlave etc? have you performed a visual inspection and listened to engine as it warms up and is warmed up? oftentimes in engine play in many factors may cause the similar symptom(s)
