Now you might think that spraying lighter gas approaching a hot engine isnt wise, however the flash /ignition narrowing of gas is roughly 400C as a result you obsession a naked blaze or spark to set it off and Ive used this method for many years without incident. doing your way through each reachable joint one at a become old 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 permit a speak to blast of gas into each area, especially those difficult to attain 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. subsequent to I unplug it and govern the motor, the car runs argumentative and at 850ish. I can lonely 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 all this. I don't think the tps has that much manage in the substitute of rpm though? I think it only adjusts it in the region of 1k..
