it was fine when i parked it two days ago.now engine is surging-headlights go dim then bright,speedometer is not working,if i rev the engine in neutral the speedometer goes crazy.we've had a lot of freezing rain and snow lately,everything is pretty wet,i wonder if this is a factor?also if i'm driving along in 4th gear and downshift the speedometer will go nuts for a second and then drop back down to zero.

    thanks for replying.i dont have a tach but my speedometer is malfunctioning.in neutral and stopped,when i rev the engine the speedometer goes crazy,jumping all over the place and if im driving along it doesnt work but when i downshift it will jump all over the place.also my headlights are dimming and brightening and engine is idling erratically.ive read that the problem may be some wires that rub on the intake manifold bracket and eventually wear through and cause this problem.I will check that when i get a chance.any ideas?
