2010+ Volant CAI issues resolved?

[wolenzo]

I just purchased a 2011 LTZ and starting to look into performance mods. I'm leaning towards the Volant but have found people with CEL issues even when they installed it correctly (disconnecting negative battery cable). Sounds like Volant has been great about helping to fix the issues but it sounds like the CEL has come back on some owners.

Are there any 2010+ owners successfully running volant CAI's? Or owners successfully fix their volant CAI's?

I've heard of similar problems with the supercharged Cobalt SS. I'm not familiar with the Volant intake. Is the filter oiled? If so, clean the MAF and try wiping down the filter to reduce excess oil. Either way, I recommend getting a custom tune to help adjust the computer calibrations to help out.

I thought the problem was ONLY with the '09 model year, but I am not sure about that (I have an '09, and do know that the problems at least BEGAN with the '09s, since a sensor was moved in '09). You'll have to dig around and verify the correct answer.

I threw another P0442 code recently without the Volant. I had removed the Volant because the last code I got with it I couldn't clear. I may have something else going beside the Volant, so I'm not sure exactly what's causing the CEL, but can at least clear the infrequent CEL without the Volant on the truck.

It's a shame, because the Volant sounds absolutely awesome. If folks with '10+ trucks aren't having CEL problems with the Volant, I'd recommend the unit for sure.

A quick Google search for "2010 Chevy Tahoe DTC P0442" pulls a long history of this error code on the Tahoe. P0442 is for EVAP Emmission Control System Leak (small). The fix tends to be simple. Just replace the fuel cap.

Here's just one forum with this info:

Incidentally, what's the best way to get a new cap? Just go to the parts counter of your local Chevy dealership and order one? Or...?

KMeloney - I've come across your posts the most regarding the CEL but now it sounds like it might not be the Volant. I might take a gamble and just go with it. Update us on your CEL if you change your gas cap soon. Thx.
