There was a short in my stereo that was causing my battery to drain totally down to nothing. So i got a new battery, ripped out the stereo, and now my car is missing a little bit, and the tach is jumpy as hell.
Any ideas?

 

maybe your battery ground cable isn't in very good shape. sounds like maybe a small break in the wire was disturbed during battery replacement?

 

spark plug fry?

 

i think im gonna start with new plugs dist cap and rotor since all are pretty old.
it just sucks because im selling the car, and i need it gone, and now its running like ****.

 

if you changed the battery, and now the tach is running funny like that, your ignition isn't the problem. you have a bad ground somewhere. all your computers are grounded to the battery, so if i was you, i'd save your money and check that ground wire.

 

thx
