Buying advice

Consider your vehicle's make and the level of diagnostics you need. For simple spark checks, a basic tester under $20 works. If you need full OBD2 and ignition system analysis, invest in a scanner like the Innova 5568 or Autel MX808S. Ensure the tool supports your vehicle's protocols (e.g., CAN) and offers live data for deeper troubleshooting.
