Now you might think that spraying lighter gas vis--vis a warm engine isnt wise, however the flash /ignition reduction of gas is practically 400C appropriately you craving a naked flare or spark to set it off and Ive used this method for many years without incident. conduct yourself your pretentiousness through each reachable joint one at a period and you should locate it. I use a slightly flattened piece of brake pipe and some rubber hose from the can of lighter gas to have the funds for a spraying wand and allow a forward blast of gas into each area, especially those difficult to achieve when large implements.
I did re-check them tho. The master tech did extensive tests upon the ventilate flow meter and said it was good. taking into account I unplug it and govern the motor, the car runs harsh and at 850ish. I can lonely guess that my new 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 control in the rotate of rpm though? I think it unaided adjusts it with reference to 1k..
This could be a large vacuum leak ,with the MAF combined it is unaided measuring the ventilate that is getting past the MAF, appropriately if the intake manifold is sucking in ventilate the freshen to fuel ratio will be no question out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. with carb cleaner vaporizer spray can in the area of the hissing taking into consideration the engine processing and next you listen the engine stall or rev innovative there is the leak ,could be a bad vacuum hose bad gasket on the manifold.
