I recently changed my spark plugs and wires.
I got a check engine light
and on my carmd I got a indication spark plug 6 had a problem.
Problem was the wire came off while driving short distance.
I put the plug wire on and disconnected my negative battery terminal to get rid of check engine light.
My carmd still gives me a yellow light and suggests proceed with caution.
How long would I have to drive my car to reset computer codes and get a green light?
