Question about 2004 Chevrolet TrailBlazer
I had the Service Engine Soon light come on my 2004 GMC Envoy. It has code P0410 Secondary air injection code and P0128 Coolant temp code. Now it seems to be losing power when you driving around 40 mph it will gain power and then lose power. At the red lights it seemed like it wanted to go dead. Will either of these codes be causing me to lose power or is it something else?
Most ecu controlled vehicles have a 'limp home'mode if 2 or more fault codes are stored,it is designed to get your attention before damage is caused and to get you to the nearest w.shop to fix,i would have codes cleared and retest vehicle,it is the cheapest and 1st option for any shop,some late models even have excessive mileage past service interval in the 'limp' program
