1990 gta 5.0 project Ive been working on. One day the tachometer stopped working and when I tied to drive it it felt like the e brake was on.This has happened before with the tachometer not working but I rarely drive it so idk if its he first time it locked up too. When it happened I tried everything to unlocked it going through P.R.N.D.D1 and All that nothing worked. Wouldn't with car off in N. Either.
So I unplugged batt for few days.
Today i went to go look at it, tachometer worked, now it's fine no locking up
Any idea what could have caused this.
