My engine light came on after I changed the oil and air filter & it misfires on 2007 Chevrolet Trailblazer

Any suggestions on what I can do to correct this problem?

Look back at the air filter replacement. If an air hose got pulled off or if a connector got pulled off... that is probably the issue. Eric Sevim - ASE Master Certified Technician A+ Japanese Auto Repair - San Carlos CA 94070
