Smog Test Preparation
 

Daughter has 236K on her 01 4cyl---I am going to change the oil, air filter, pcv valve, spark plugs and have her put in the gas some injector cleaner before she leaves for the 2 hour drive up to my place----Can you think of any other small things to do that might help---Thanks

Happy

my mechanic said to try cataclean. They have had some successes with that
