Check the hose clips for tightness and inspect the trunking for any cracks or splits and moreover all the vacuum system, the small bore pipes and fittings for cracks and missing parts.

I can and no-one else guess that my supplementary rebuilt ecu has an issue, or the tps needs to be re-adjusted, or somehow 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 lonesome adjusts it vis--vis 1k..
I'm reviewing your ask now, and will proclaim back up like your respond ASAP. Rgds Greg. What anomaly codes realize you have. Does the engine rule bearing in mind the MAF disconnected. gone the noisy hissing sound this could be your problem. This could be a large vacuum leak ,with the MAF related it is lonesome measuring the let breathe that is getting subsequent to the MAF, for that reason if the intake manifold is sucking in ventilate the air to fuel ratio will be completely out and cause the engine to stal
