The removal of electrical power from the engine erases idle memory from the PCM, the computer where it is stored. Now if you clean the throttle body bore you have more air going around the plate causing a higher. This will work most2000 and newer Toyota models. HI All,I have a 2003 Hilux D-Cab 2. The reason I cleaned the throttle body was mostly because of that horrible low idle when I replaced the battery earlier this year. If available, try swapping in a new throttle body to see if that fixes the problem. An independent mechanic also thought they couldn't be cleaned.
