Check the hose clips for tightness and inspect the trunking for any cracks or splits and as a consequence every the vacuum system, the small bore pipes and fittings for cracks and missing parts. The best quirk to find a leak is to have the engine handing out and warm and next spray can lighter gas /propane or brake cleaner approaching each joint in turn. If the engine rev s up you ve found your leak.
I did re-check them tho. The master tech did extensive tests upon the expose flow meter and said it was good. later than I unplug it and direct the motor, the car runs aggressive and at 850ish. I can by yourself guess that my supplementary rebuilt ecu has an issue, or the tps needs to be re-adjusted, or anyhow 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 forlorn adjusts it in this area 1k..
have you looked into throttle body coking and/or combustion chamber/valve carbon buildup? are you occurring 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 happening and is warmed up? oftentimes in engine feint many factors may cause the similar symptom(s)
