I may ask you to take effect testing in my stead. If chemical analysis is needed and you would rather not feign testing, I can give my best advice, Fuel pressure?
I'm 1500 too high.. or more. It's boggling to me how this burden has morphed into various idle problems and has everyone perplexed.. or as a result it seems. I've been dealing similar to this in the past July.. makes me appreciate my 240z 10 period more.My daddy owns an sc400 and its been in point of fact fine to him.. I'm having a difficult epoch not instinctive prickly subsequent to this purchase. I do quality behind its a fine car though. Motor sounds gorgeous and is super serene afterward presidency right.
considering I begin the car, the engine surges taking place in the company of 1200 and 2000 rpm encourage and forth. I tainted the IAC and the TPS in the manner of no tweak in symptoms. I have noticed that several Lexus SC's have this same issue. Prior to this I would have to adapt the idle promptness screw to lower the rpm and it would preserve for a while. Now, the engine is forever surging to the reduction where I cannot drive it for warning of broken to the drive train. Any experienced solution?
