Now you might think that spraying lighter gas in this area a hot engine isnt wise, however the flash /ignition narrowing of gas is roughly 400C for that reason you dependence a naked flare or spark to set it off and Ive used this method for many years without incident. affect your habit through each realistic joint one at a get older 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 meet the expense of a spraying wand and allow a concentrate on blast of gas into each area, especially those hard to accomplish similar to large implements.
Thanks for your response. I just checked what you mentioned, that I hadn't already checked, except fuel pressure.Let me tell you a little more very nearly the hardship history. It currently has a master tech official idle expose rule valve and tps installed. without heartwarming anything, the last (used) ecu and my original, would direct in the car without this symptom.
past I begin the car, the engine surges happening together with 1200 and 2000 rpm back and forth. I distorted the IAC and the TPS gone no modify in symptoms. I have noticed that several Lexus SC's have this thesame issue. Prior to this I would have to adapt the idle speed screw to degrade the rpm and it would hold for a while. Now, the engine is continually surging to the reduction where I cannot steer it for terror of damage to the drive train. Any experienced solution?
