They did a diagnostic on my car and first told me it needed spark plugs because their system read multiple miss fires,I got the tuneup,no improvement,another diagnostic test and they told me I a catalytic converter and an 02 sensor. No improvement. I brought the car back and one of the guys named Ash asked me if I just wanted to pass emissions, I said no I want my car fixed, I didn't even need emissions idiot ,they wanted to keep doing guess work and continue to run up a bill. Avoid them at all cost. My car still has a long delay after hitting the gas and shuts of if I have the AC on and stalls. They got be but never again.
