I got a code reader so i can run the codes off the stang. The manual it came with says I have to use a timing light to check ignition timing before i can run the codes with the key on engine on. Is that a must?
Okay so I have to pick up a timing light then. The code reader I picked up was about 30 bucks and doesnt have a digital display...does that sound about right or is there something better out there?
