In these kind of temps what rpms should be ok I'm getting almost 2k Rpms but lowers to 1.2k after warm In the summer cold gets me 1.4k but lowers to .9k rpm after warm Is this normal for me or not please help |

Mostly I agree but the throttle opening diaphragm is easy.
Its an aluminum colored accordion sort of thing on the throttle lever. There is a vacuum hose running from it to the throttle body, only 6" long. When the motor looses vacuum, like it were going to die, the diaphragm extends out and brings the throttle back up so it won't die. So to test it you just unhook the vacuum line and see how high the idle is when its opened. There is a small set screw to adjust exactly where the idle sits when its opened. -------------------- Bust a Deal; Face the Wheel.

Is this when the engine is already at temperature or cold? -------------------- Brand new 6gc owner! (sort of 2011)
