Guys,

I'm having trouble with my brother's 2001 Z28. When he drives the car for a few miles, he gets a P0200 code and the CEL lights starts to blink. I know that the blinking light means a misfire, but the strange thing is that the light will go away after leaving the car sitting for a few hours. I know that the P0200 light is a "fuel injector circuit malfunction," and have read up on it here on the forum. I've checked all of the FI connectors and they are all on there good.

Question: What can be causing the P0200 light to come on after a shirt drive?
