I thought I was just going in for an oil change. But since I was experiencing some hesitation when I'd leave a stop light, I asked the mechanics to let me know what else I needed. Turns out the valves needed adjusting.While I didn't expect the expense, I consider it well worth it, as I drove away from Morin Brothers feeling as if I was driving a car with a brand new engine....I got away with a DEAL!!! Thank you Morin Brothers!!
