Check the hose clips for tightness and examine the trunking for any cracks or splits and plus 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 admin and hot and subsequently spray can lighter gas /propane or brake cleaner almost each joint in turn. If the engine rev s occurring you ve found your leak.
I did re-check them tho. The master tech did extensive tests on the air flow meter and said it was good. afterward I unplug it and manage the motor, the car runs unfriendly and at 850ish. I can without help guess that my new 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 direct in the substitute of rpm though? I think it lonely adjusts it roughly 1k..
