QUESTION: Firebird   97    6cyl  3.8

Answer
that engine is noted for bad plug wires in that car So I would look there first get a "GOOD" set of wires SC delco or ANAP premium 7MM wires. Id the MAP sensor is damaged in any way I would replace it but a map sensor is not going to cause a 1 cylinder misfire It would effect all 6 cylinders. Good luck :)
