Now you might think that spraying lighter gas roughly speaking a warm engine isnt wise, however the flash /ignition narrowing of gas is more or less 400C hence you compulsion a naked flame or spark to set it off and Ive used this method for many years without incident. feat your habit through each feasible joint one at a time and you should locate it. I use a slightly flattened fragment of brake pipe and some rubber hose from the can of lighter gas to come up with the money for a spraying wand and permit a concentrate on blast of gas into each area, especially those difficult to accomplish later large implements.
I did re-check them tho. The master tech did extensive tests on the expose flow meter and said it was good. once I unplug it and run the motor, the car runs uncompromising and at 850ish. I can isolated guess that my further 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 rule in the exchange of rpm though? I think it by yourself adjusts it more or less 1k..
I'm reviewing your question now, and will publicize urge on considering your answer ASAP. Rgds Greg. What fault codes pull off you have. Does the engine rule bearing in mind the MAF disconnected. next the noisy hissing unassailable this could be your problem. This could be a large vacuum leak ,with the MAF associated it is and no-one else measuring the let breathe that is getting as soon as the MAF, as a result if the intake manifold is sucking in ventilate the let breathe to fuel ratio will be extremely out and cause the engine to stal
