Help!!!!!!
They only find trouble codes that trigger engine lights. And half the times they are wrong. An Autozone guy cannot tell you exactly what is wrong being non ASE certified, and from a 15 second scan. The dealership Diagnostic takes 30 minutes and it scans every single monitored part of the truck and finds out exactly what is wrong, and why, and what needs to be done. Well worth the $60 imo.
huh?
A tune up is basically changing the spark plugs and spark plug wires. very easy thing to do. Just remember the length of the wires because they are all different. Only hard part is getting behind the engine.
