I brought my car in for an oil change somewhere else and unbeknownst to me with a smoking positive terminal to my battery. I called 2 guys and they were thankfully able to get me in to fix it. It was the end of their long day and even when it turned out to be a little more than anticipated they all remained positive and lighthearted. I would trust them for anything in the future. Yes, the price was great but nothing beats kind, honest, professional and knowledgeable. Thank you guy's so very much and it was a pleasure to meet each of you.

Common questions and tips from our work with Friendship customers.
- Does a code tell you exactly what is wrong?
- No. A code tells you which system flagged a problem and under what condition, not which part failed. A lean code, for example, can come from a vacuum leak, a weak fuel pump or a dirty sensor. Testing the system is what turns a code into the correct repair.
- Is it safe to drive with the check engine light on?
- If the light is steady and the car drives normally, you can usually drive it in for a scan soon. If the light is flashing, that usually means an active misfire that can overheat and damage the catalytic converter. Ease off and get it looked at right away.
Tip
Write down the symptoms before you call
Note when the problem shows up: cold starts, highway speed, braking, turning, or after rain. Write down any sounds, smells or vibrations and whether a warning light came on. Those details help narrow a diagnosis and point testing in the right direction from the start.
