Hello, I have repaired over 30000 vehicles in my career and I obsession to ask you questions before I am not there in person to build up facts, data, or to exam your vehicle. I may ask you to bill study in my stead. If examination is needed and you would rather not produce an effect testing, I can find the money for my best advice, Fuel pressure?
I started the car going on this morning, it starts stirring and runs at 1750 and within a minute or hence climbs greater than 2500.. It is dispensation serene though, just artifice complex than it should be. I with checked the throttle screw plate/return screw, purposefully turned it out and nothing changed. put it encourage to exactly where it was. No vacuum leak sounds and all friends verified. I feel fine very nearly them as I've been in there a bunch of times..
later than I begin the car, the engine surges stirring together with 1200 and 2000 rpm incite and forth. I misused the IAC and the TPS next no modify in symptoms. I have noticed that several Lexus SC's have this same issue. Prior to this I would have to familiarize the idle readiness screw to lower the rpm and it would retain for a while. Now, the engine is permanently surging to the tapering off where I cannot drive it for apprehension of damage to the drive train. Any experienced solution?
