Sticking Tach on 79 T/A with Olds 403 motor
« on: June 22, 2012, 10:35:58 PM »
What would cause my Tach to stick at around 2700 RPM's and go no further up?* If I have the car in park it will stick momentary at 2700 RPM but if I keep pushing down on the gas pedal it will break free and continue to climb up into the yellow, untill I stop pushing on the pedal.* This only happen's when the car is in park and no load is on the engine.* Once the transmission is in drive I cannot get the Tach to go above 2700 RPM.
Any ideas?
Thanks.
