83projectbrat Posted December 7, 2003 Share Posted December 7, 2003 im driving down the road in my 89 (fuel injected) gl wagon and im about 3-4,000 rpm. ill let off the gas and the motor sounds like it just died then jumps back up to where it should be on the tach. its hard to explain. what could it be? its not really a problem, but i just dont want it to die all the way some time and not start. matt Link to comment Share on other sites More sharing options...
myossfeece Posted December 7, 2003 Share Posted December 7, 2003 Sounds like possible elec. problem. I notited in my soobs if the key is off and your being towed or otherwise rolling with it in gear it will read 0 on the tach. Turn the key on while still rolling and the tach will read correct engine speed. If you let off the gas and when the motor acts up does the tach go to 0 as well?
