Subject: Re: Mono-blade phenomena by 1989GTA on 2009/8/21 0:41:46 Here is my story. I have the AS&M monoblade on 355 modified TPI system. I drove it for quite awhile with no problems. Then from time to time the idle would not go below 1100 rpms. As time went by it would happen more frequently. So I finally decided to investigate the cause. I noticed that the throttle body would stick open ever so slightly. I could easily manually close it and the idle would go down to around 775rpm like it should. The next time this happened I confirmed the throttle was still open a little. I just shut off the motor and the throttle closed all the way. So I went to the hardware store and looked through their selection of springs and bought a light weight spring of the right size and length and installed it to help in the return of the throttle. The problem went away and has not come back. Easy enough fix. By the way this problem also exist with other throttle bodies just not only the monoblade. The ones I have seen it on are usually high performance cars. |
