Hello, So recently over the past 3-4 days I noticed my truck started to have a rough idle and then it wasn't wanting to start. There wasn't a check engine light or any alert light.

Asked by Oct 29, 2015 at 01:26 AM about the 2002 Chevrolet Silverado 1500HD LT Crew Cab Short Bed 2WD

Question type: Maintenance & Repair

So my fiancĂ© changed the spark plugs. And now the problem is still there but a little worse and a service engine light has come on, and it flashes when I accelerate. Its stuttering when accelerating and still idling hard.  Any Ideas?

You have fuel injection... and your fuel is controlled by a computer. You might have a bad mass air sensor, or the throttle body needs to be cleaned. Google those for your truck type and you can clean/replace them yourself.
