The yellow "check engine" light has been on for about 6-months. So I finally drop the car off for service and they say the secondary air pump is ABOUT to fail. i.e.; it works fine now, but it is about to fail. They want $580 parts/labor to replace it. This sounds like a $10 PCV valve.

Can someone explain what this pump does and should I even replace it? If the pump does fail, will it leave me stranded? The car runs fine and just passed the VA emissions test.

Thanks,

It takes about 30-45 minutes to change it. Not sure how much they go for new, I picked one up used.

First time about 4 months after I bought the car. About a week after I got it back the check engine light came on again. Turns out it was the exact same problem. Luckily this was all under warranty (whew! I only had a few months left). I asked the dealer about it and he they told me these pumps go bad quite often. Apparently so!

probably crappy while still cold. If you continue to run rich for a long time, you can experience cat convertor failure sooner or possibly o2 sensors needing to be replaced.
Not to metion that light is annoying...but hey, you lived with it for 6 months....

I'm surprised the CEL bulb didn't burn out ;-)

Looks like #4 will be in soon. Thank God I only had to pay for the first replacement.
