Question about 2004 Chevrolet TrailBlazer
Chek engine light continue to come on . All fluids are good and filters are clean, Gas cap has been replaced twice. smoke test was done and it was recommended to change gas tank. Dealership not sure of problem. l
Check engine light has **** to do with any of what you listed. It only relates to pressures and sensors. Retorque your throttle body, check resistance on your sensors and if that doesn't work change the map sensor. They're bad on these vehicles
