How often do you replace the coil in a 2007 Chevy Tahoe LTZ 5.3 liter engine
Remember there are 8 coils on the 5.3 V8 engine any they fail at different times.
You only replace them as they go bad. It's not a tune up item like the plugs and wires. Unless you have a code for one of them chances are they are fine
Mass air flow sensor i had same problem changed it runs great now im sure thats it
