My 2001 3.8 Camaro supposedly needs a new Mass air flow sensor. When I investigated the sensor I found that the car had been modified by the guy before me. A few inches before the hook up the wires had been cut and replaced by another hook up. The three wires were soldered with the other three wires; I am worried that that he wired it wrong and the $160 part will be a waste. The three stock wire colors are black with white, yellow, and orange. The wires are the same for the 3.8 engine and the LS engine, I just need to know the order the wires go into the sensor. Thanks!
