Tech / General EngineIs your car making a strange sound or won't start? Thinking of adding power with a new combination? Need other technical information or engine specific advice? Don't see another board for your problem? Post it here!
well one day my tach decided to stop workin, then it would work after i drove around for awhile, i have takin it out to put the needle back at zero, it wrapped out to 7000 some how lol, and when my car is running it usually sits at 2000-2500, and when i rap my engine up to like 4000 it shoots down to zero really fast, then goes back to 2500
any help would be appreciated, its auto trans, but i still like to watch my tach since im gonna have a 300hp+ motor heh
Sounds to me like the tach is fornicated. Just get another one at the boneyard. Make sure you get the little circuit board on the back of it, and that you get one out of a car with the same # of cylinders as yours.
