Check the hose clips for tightness and examine the trunking for any cracks or splits and furthermore every the vacuum system, the small bore pipes and fittings for cracks and missing parts. The best showing off to locate a leak is to have the engine direction and warm and after that vaporizer lighter gas /propane or brake cleaner approaching each joint in turn. If the engine rev s going on you ve found your leak.
I did re-check them tho. The master tech did extensive tests upon the air flow meter and said it was good. subsequent to I unplug it and govern the motor, the car runs sharp and at 850ish. I can deserted 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 direct in the swing of rpm though? I think it unaided adjusts it around 1k..
