2002 Chevrolet Corvette Long Term Road Test


2002 Chevy Corvette Z06: A DIY Special

We've had enough of the run around. We are going to fix our 2002 Chevy Corvette Z06 ourselves. At least that's the plan.

We're convinced (mostly) that our detonation problem is due to a faulty knock sensor. In the last Z06 post Mike Schmidt mentioned that our research turned up GM Technical Service Bulletin No. 02-06-04-023A, dated June 2002. Condition: Some customers may comment on a mild to severe engine ping, usually worse during acceleration. Cause: This condition may be the result of corrosion of the rear bank knock sensor due to water intrusion into the sensor cavity. Correction: Replace the rear bank knock sensor and build a dam around the sensor using RTV to divert water away from the sensor.

So we're going for it. Tomorrow morning at 9 am the Corvette, myself, Josh Jacquot and Jay Kavanagh are meeting at my house. And the wrenches will fly. Before he arrives Jay will buy two new knock sensors and a couple of intake manifold gaskets. I will also make a purchase; beer, which I plan on drinking while Josh and Jay fix the car.

By noon, the Corvette will either be fixed, on a flatbed, or just as sick as it was when we started this stupidity.

Wish us luck, we'll let you know what happens. In the meantime, enjoy this awesome David Kimble cutaway of the 2002 Corvette Z06 that I found on GM's media site today.
