Need Help....??? speedo makes car idle high? I dont know where to best post this... i have a 94 Z28 383 LT1 T56 running obdII. when i had my car tuned i didn't have the speedometer connected.. due to wrong VSS connector. now i replaced the pigtail with the correct one from the dealer and my car idles over 2200 when the speedometer is working. shifting through the gears and everything? as soon as i come to a complete stop the car idles back to normal? if anybody has any ideas on what the problem may be im all Ears
Any ideas?
