Hello, I have repaired exceeding 30000 vehicles in my career and I craving to ask you questions since I am not there in person to gather together facts, data, or to test your vehicle. I may question you to produce a result testing in my stead. If laboratory analysis is needed and you would rather not be in testing, I can find the money for my best advice, Fuel pressure?
I started the car happening this morning, it starts occurring and runs at 1750 and within a minute or for that reason climbs higher than 2500.. It is management mild though, just way far along than it should be. I moreover checked the throttle screw plate/return screw, purposefully turned it out and nothing changed. put it assist to exactly where it was. No vacuum leak sounds and all links verified. I vibes good virtually them as I've been in there a bunch of times..
later than I begin the car, the engine surges in the works amongst 1200 and 2000 rpm incite and forth. I misrepresented the IAC and the TPS past no correct in symptoms. I have noticed that several Lexus SC's have this same issue. Prior to this I would have to acclimatize the idle promptness screw to lower the rpm and it would support for a while. Now, the engine is forever surging to the dwindling where I cannot steer it for terrify of broken to the steer train. Any experienced solution?
