Please help...93 N/A high RPMs
i just bought a 93 supra n/a. when i start it up RPM goes down to 800 but once i press the gas it goes up to 1300-1500 and it just stays there.
i took it to the toyota dealer. they cleaened the trottle ....and now it works at even highter RPM's 2000-2100. they said they need more time to play around with it....so i thought would ask here.. also at 60mph its at 3000 rpms...is that normal? whats the problem? thanks |

so i took it home and disasambled the idle control motor cleaned it and put it back on the car....i started it up it worked at 700rmps for 1 minute and then it went back up.... i tried to do it again but it wont go down like it did the first time. so i'm not sure if that would be the problem or the trottle position sensor or something. i'm gonna buy used idle contorl motor if i find one from sc300 or something hopefully it will fix it. WHATS LEFT? lol :/ :/ |

I agree swapping the iac motor is another thing that you could try. I believe the TSRM has specific steps you can take to verify the correct (or faulty) operation of your IAC motor. Disclaimer - it's VERY hard to troubleshoot problems like this over the internet, without having the car here in person. If you don't mind the exteme limitations of trying to troubleshoot like this, I'll stick with it for as long as you would like. Please keep in mind this type of troubleshooting could lead to some wasted expense and extra time for you. Using the TSRM would be one way that could be more efficient. Note: The TSRM (Toyota Supra Repair Manual) has a comprehensive set of troubleshooting steps that covers almost every problem. It'll pay for itself several times over if you want to work on your own Supra.
