I think I had some bad gas. Had a "knock sensor see dealer" code. I was able to clear the code with a code reader. But the check engine light is still lit.I have good oil pressure, good temp, good volts...ran it it my driveway for 10 min, any ideas?

I cleared the codes and the CEL is still on. The "knock sensor see dealer " message is gone.Comment

Could be the temp sensors on the exhaust manifold riser/elbow going bad if this is happening and your operating temps are normal. Try unplugging them and see if that makes the light go away. I know PCM eventually eliminated them on the zR6 and other members have unplugged/ taped off the leads when their sensors go bad as well.Comment

And certainly it's money well spent if you're not up-to-date, change that silver fuel filter on the left-hand side. Also I add stab-il 360 to my fuel as it measures. I think it's 1 ounce per 10 gallons for valve life.
But I figure all the fuel system upkeep is cheap insurance either way. Certainly not a bad idea if you're still chasing potential problems

On top of the exhaust manifold riser.

Did you disable power from the batteries after resetting the codes? Did you use codemate to clear them?Comment

We had the manifold air sensor warning just come up on our boat with the red light but without doing anything, within a few seconds it turned off. Does anyone know what the first step in troubleshooting this should be? We have a 2007 236 with the ZR6 engineComment
