Chevrolet Q&A  Ask Your Question  2007 Chevrolet Suburban 1500
Question: What causes the engine to lose power? "Reduced engine
power" message.    shayninator, San Diego, CA, October 15, 2013,
15:25  Out of nowhere my check engine light comes on, and I lose
power. "Reduced Engine Power" message comes on and signals that
I need to service stabilitrac. Well I took it in and they
replaced the spark plugs and wires and reprogramed the throttle
body. Well all was good for about 4 days and then the same thing
happened. I also have been losing oil a little quicker than
usual. When it does happen I pull of to the side of the road,
shut the engine off, open the hood to check for any burning or
anything and nothing. I close the hood, start it up and it moves
on. Not sure if this is a trend with this model. The tell me
that I may need to get an engine rebuild but can't tell me why
or diagnos the problem.  2 Answers Flag This
