Now you might think that spraying lighter gas approaching a hot engine isnt wise, however the flash /ignition reduction of gas is about 400C therefore you obsession a naked blaze or spark to set it off and Ive used this method for many years without incident. discharge duty your habit through each practicable 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 give a spraying wand and permit a talk to blast of gas into each area, especially those difficult to accomplish with large implements.
Its as well as worth getting the fuel pressure checked as if this is low due to a blocked filter or faulty regulator or even a sick pump will all upshot in insufficient fuel subconscious delivered to the engine. Might with be worth cleaning out the idle readiness direct motor / valve as these get clogged taking place as soon as carbon and some brake cleaner washed through helps free things off.
Hello the TPS does have an effect on switching the car into idle mode suitably I'd recommend to create certain the throttle plate is 100% closed and not slightly beached subsequently carbon. and next acclimatize the TPS hence that the IDL attach is continuous to the E2 pin as soon as the throttle is closed, and get into circuit with the throttle is just cracked. Don't cause problems about any voltages, the IDL retrieve is the truly important one.
