Check the hose clips for tightness and inspect the trunking for any cracks or splits and next every the vacuum system, the small bore pipes and fittings for cracks and missing parts. The best quirk to locate a leak is to have the engine processing and hot and then spray lighter gas /propane or brake cleaner approaching each joint in turn. If the engine rev s in the works you ve found your leak.
I did re-check them tho. The master tech did extensive tests on the ventilate flow meter and said it was good. with I unplug it and manage the motor, the car runs unfriendly and at 850ish. I can lonely 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 every this. I don't think the tps has that much direct in the alternating of rpm though? I think it unaccompanied adjusts it regarding 1k..
have you looked into throttle body coking and/or combustion chamber/valve carbon buildup? are you in the works to date upon every maintenance; spark plugs fuel filter pcv vlave etc? have you performed a visual inspection and listened to engine as it warms happening and is warmed up? oftentimes in engine con many factors may cause the similar symptom(s)
