As the title says (the idle is around 950/1000) but it doesn't drop down to that very fast, it is almost like driving a vehicle with a sticky throttle. I have just installed a new (rebuilt by Jeff Bowlsby) relay board and cleaned up my grounds and cleaned the engine compartment. Any ideas what is going on?

Ian Stott Moncton Canada Could your throttle be sticking? Mine did, causing the idle to hang until I bumped the accelerator peddle. I cleaned it with carburetor cleaner. Its been said that a failing deceleration valve can produce a vacuum leak. You might check out Anders Since the TPS asserts a separate "idle circuit" when the throttle closes, I can't reason why the idle would ever "hang," unless the TPS is maladjusted or there is a physical problem with the throttle? That's a question not a statement of fact. |
