wierd code

[f5fstop]

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.

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.
