Question about 1985 Chevrolet Chevy
Just washed engine and compartment now truck is idling very high. Pulled batt cables off to reset but no change...strange?
You might have gotten the throttle sensor wet, to the point that it shorted out. the throttle sensor is on the side of the throttle body / by the accelerator linkage. unhooking this sensor while the engine is running, will make the engine idle at or around 1500rpm....when you disconnect the sensor while the engine is running, and the RPMs go DOWN, then the sensor could be in the process of malfunctioning. if the RPMs go UP then the sensor is completely bad. either way, it will need to be replaced, and these are about $10 - $30, depending on where you get them.....places like auto-sone and napa have them in stock ALWAYS. also, invest in a diagnostic tester, because they really come in handy in situations like this and you can find one for as cheap as $25 at auto-zone AND napa.
