Took my car to express auto due to a check engine light... I new from a prior scan that it was an o2 sensor and asked them to check for a short in the wire... I phoned them at 330 to see if my car was done and was told they were just pulling it in to the shop... I went to pick it up at 5 before they closed and it was sitting out side done... They found the wires shorted out like i told them.

The bill was for $650 .I asked how much because i was told there rates were $100/hour I was told that because it was hooked up to there diagnostic machine it was $180/hour x 3 hours...
