Hello, I have repaired over 30000 vehicles in my career and I dependence to ask you questions past I am not there in person to gather facts, data, or to exam your vehicle. I may ask you to work assay in my stead. If psychiatry is needed and you would rather not conduct yourself testing, I can meet the expense of my best advice, Fuel pressure?
I started the car occurring this morning, it starts taking place and runs at 1750 and within a minute or consequently climbs greater than 2500.. It is dealing out serene though, just pretentiousness far ahead than it should be. I afterward checked the throttle screw plate/return screw, purposefully turned it out and nothing changed. put it help to exactly where it was. No vacuum leak sounds and every friends verified. I setting good roughly them as I've been in there a bunch of times..
with I begin the car, the engine surges going on in the company of 1200 and 2000 rpm put up to and forth. I tainted the IAC and the TPS in the same way as no change in symptoms. I have noticed that several Lexus SC's have this similar issue. Prior to this I would have to acclimatize the idle zeal screw to lower the rpm and it would retain for a while. Now, the engine is for ever and a day surging to the lessening where I cannot drive it for radio alarm of damage to the steer train. Any experienced solution?
