wierd code
 
Driving down Lemmon Ave. here in Dallas, all of a sudden no power. I mean I can't go over about 5 miles per hour. On comes the check engine light and a code that says "reduced engine power". No **** Sherlock! I turn off the vehicle and turn it back on to recycle. Check engine light still on but I have full power. I make it to the dealer half a mile away. They give me an H3 loaner, call me 2 hours later and say all I needed was a software update. No charge. Whew! I thought the worst but all is well. Anyone else had " reduced engine power"? Scary.

That's the FIRST thing I've always been asked to check when using OnStar. GM needs to fix that problem.:rolleyes:

You guys are getting reduced power with the fuel cap off? After a set time it is supposed to set a vapor leak code and turn on the light, but I have not heard of a reduced power mode.
Next time the programmer is over I'm going to have to check with him on that one.:confused:

My problem was not a fuel cap issue. At first we thought alternator, but it was a software glitch known to my Tech and he merely uploaded new software.

I had the code come on by my gas cap being loose. also by losing all power sounds like you cat conv. is bad, I replaced one at 50000 miles. vehicle lost all power would only go 5 mph, not sure when the warranty runs out, but it was still good for the cat conv at 50000 miles

Converter warranty is different between states. It should be in the owner's manual what the warranty is for each particular state.
