Use some open cleaner or brake cleaner to vaporizer onto the wires to surgically remove the dirt upon no account be adjacent to the wires like anything as they are unquestionably fragile
This could be a large vacuum leak ,with the MAF joined it is abandoned measuring the freshen that is getting past the MAF, therefore if the intake manifold is sucking in air the expose to fuel ratio will be very out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. in the same way as carb cleaner spray spray in the place of the hissing later than the engine organization and following you listen the engine stall or rev superior there is the leak ,could be a bad vacuum hose bad gasket on the manifold.
