Connor280ZX Posted June 1, 2014 Share Posted June 1, 2014 How it starts off it basically when the engine is revved, the needle will not keep up quick enough with the engine speed, and when let down to an idle, the needle wont drop below 1400-1600 Rpm. I know it's not just idling high, becuase i can hear the cam loping. When i turn the key off, the needle sticks. It sometimes will fall down slowly though. When it does stick, i can tap on the cover and it will start to fall down to zero... Could the internals just need a bit of oiling? And yes, this is the original tach with the original ignition system. Quote Link to comment Share on other sites More sharing options...
Connor280ZX Posted June 9, 2014 Author Share Posted June 9, 2014 Today, it got hot inside the car when i went to start it. When i did start it, the tach slowly started to climb and stopped at 4400 RPM though the engine was idling... When i turned the key off it stuck exactly there and didnt came back down for an hour or so. Now im starting to think its an internal problem.
