Check the hose clips for tightness and inspect the trunking for any cracks or splits and also all the vacuum system, the little bore pipes and fittings for cracks and missing parts. The best pretentiousness to locate a leak is to have the engine admin and hot and later spray can lighter gas /propane or brake cleaner going on for each joint in turn. If the engine rev s stirring you ve found your leak.
I did re-check them tho. The master tech did extensive tests upon the let breathe flow meter and said it was good. later I unplug it and direct the motor, the car runs harsh and at 850ish. I can unaided guess that my other 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 govern in the swap of rpm though? I think it without help adjusts it all but 1k..
have you looked into throttle body coking and/or combustion chamber/valve carbon buildup? are you occurring 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 happening and is warmed up? oftentimes in engine play-act many factors may cause the similar symptom(s)
