Ignition coil or computer?
My 91 Mustang 2.3L started running real bad today, as if it was running on 3 cyls. I checked the spark from all 8 wires and only 3 were sparking. The front ignition coil had no spark the rear 3/4. After a bit of internet searching I read it could be the DIS module in the computer. I changed the positions of the coils and got 2/4 sparking on both.
I'm thinking it's a computer issue and a waste of time/money to replace the ignition coils.
Oh also, I have already replaced the spark plugs/wires as they were due for a change anyway...
Any thoughts?
