    Wassup people,

    Having an issue with my 85 SR5 22re.
    When starting it cold or after sitting for awhile it idles rough and even shuts off if not given gas but when it finally wams up it idles pretty high about 1200rpm.

    It also idles pretty rough when a/c is on.

    Any advice would be great..... Thanx

    Sounds like a vacuum leak. Check all the vacuum lines and the junction where the lower and upper halves of the intake bolt together.

    You can spray WD-40 on any suspected parts of the intake while the engine is running and if the idle changes mark that area. **Make sure you have good ventilation when spraying the WD-40 coz it smokes when you hit hot spots.

    Gonna check and test sensors and vac leaks.
