    SC400
  1. Per this article: http://us.lexusownersclub.com/forums/index...&hl=jerking Is it a same fix for 1993 SC400? Why do the ECMs go bad? Thanks
  2. 1992 OZ Italy 16" Rims. on a 1993 SC400. Are they better than the stock rims? How good are they?
  3. It is the alternator, due to my research, i just need to be sure about it. I`ve found this article, it looks helpfull: http://www.lextreme.com/alternator.html I have replaced the alternator, and it solved the problem. Thanks everyone. Did you get a rebuilt oem or a new aftermarket? A used, good working.

  6. In my sc4, even if the car is running i get a battery light and engine could stop running if some electrical load is given. Gauges begin to dim, and so on. what is the first thing i could check here. Thanks
  7. Yes, first i spray-cleaned the valve with a carb cleaner which didnt change anything at all. Later, second time I basicaly had to take it apart and smooth its mechanisms with oil. Then i tested it with direct battery voltage, and??? It works! Put back in, start car, excelent RPMs. Very simple. Thanks.
  8. Problem Fixed! If anyone has a similar problem, you might want to check and clean the entire IDLE Air control Valve with some oil. Thanks
  9. Ok, the low RPMs were caused by a non working air flow sensor. (was code 31 airflow meter.) Now with another used working AF sensor, I get bucking 1k - 2k RPMs. already injected 1/3 pint of seafoam into valves, through air vac hose. Now i dont get any CEL. wonder what could be causing it. ? approximately $$$ for such to be fixed at a shop?
  10. hi everyone, What could cause a 1 owner SC400 with a little over 100k miles, to run rough? I already done the folowing. Cleaned idle control valve, replaced air flow sensor, Cleaned the trottle body, checked spark plugs & they look good. Doesnt seem to be a missfire. Car idles at low RPMs with uneaven exhausts.
  11. Difficult to connect the dots on all that - I doubt there's a common thread through all symptoms. One things sure, the starter solenoid or cables have a serious short circuit thing going on. If turning the wheels left or right caused the starter to hook up, that sounds perhaps like loose starter cables that may have pivoted to a position where they have shorted. Starter solenoid switch with welded contacts (worn out) can cause the symptom of being unable to stop the starter motor without disconnecting the battery. There is no likely connection between power steering, rough idle, not starting, etc. Concentrate on resolving the starter issue (being able to use the key to operate starter) before proceeding to try and sort out the other issues. I fixed it! The front left grounding rod was dissconnected. Works now. Thanks
  12. First, the car had a rough idle, the RPMs would jump from 1k to 2k continually. Then i was trying to see what the problem was with my power steering system, it did not work right. Then, while turning the steering wheel right, left, suddently, the starter started working and the engine stopped ant the same time. When i turn the key to the ON position, the starter is turning the engine and removing the key from the ingnition will not stop the starter until battery is disconnected. and the engine will not start. Remote door lock stopped working.Only 100k miles on the car. I dont know what could be the problems, seeking advice, Thanks
