Check the hose clips for tightness and examine the trunking for any cracks or splits and moreover all the vacuum system, the little bore pipes and fittings for cracks and missing parts. The best pretension to locate a leak is to have the engine organization and hot and then spray lighter gas /propane or brake cleaner all but 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 freshen flow meter and said it was good. afterward I unplug it and control the motor, the car runs brusque and at 850ish. I can unaided guess that my other 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 run in the interchange of rpm though? I think it lonely adjusts it all but 1k..
