Chevy 2007 Trailblazer Sputtering in the Morning. Code P0171 has come up in the past

Too lean = too little fuel. I would probably try the fuel injector cleaning (Techron or comparable product) first and see if that clears up the issue. Next try swapping the fuel filter since this is ...

If the engine is running and the headlights stay on then it's unlikely you have a problem with your battery or your alternator which charges it as they must have power to run. All the dash lights, ...

Vehicle dies for a couple minutes when I try to start then turns back on

More than likely it's the blower motor itself which is bad. This can be from a "dead" spot where the brushes meet the motor or what have you. Then some vibrations got it to a "good" spot and it ...
