Default Tach Jumping Crazy HELP
Car is driving fine. Came back from parents house (about an hr trip). Half way home the tach starts going crazy. My Link is still reading accurately, and the dash tach will once in a while, but jumps all over the place.
Tonight I cleaned the grounds on the exhaust side and it doesn't seem to be doing it as bad, but it is still doing it. Hopefully you guys have heard of this.. It's driving me crazy.

Thanks in advance
Michael

Check the ground on the front side of the intake. I've had mine loosen up twice and cause the same problem.
