I have a 1997 gtp with a bit over 180,000. I noticed my tach would just drop to 0 while driving and the engine would miss a bit. After reading a bit It looked like the crank position sensor. I replaced it wed. I didn't drive much at all Thursday but today (friday) it's still doing the same. The tach stops responding and I'm getting some misfires here and there. The tach stays down till I shut off and restart but then it usually drops again while driving. Anyone have this issue... what should I look at next
