I bet it's the CAI causing the problem. When you unplug the MAF the ECU defaults the A/F ratios and normalizes any issues. With the CAI you are getting more air coming in, which is causing more fuel to be dumped in, some of which can't be fully burned off and over time it seeps past the rings and into the oil.

Not a good thing for the cat either, as it has to work harder to pull the extra emissions out which makes it less efficient and shortens it's life.

Try putting the stock airbox back on and see if it stops the bouncing RPMs. If it doesn't then you may have something wrong with the MAF, but usually you'll see a CEL or at least a stored code. So my $$ is on the CAI.

Better memory than mine, sir :beer: 2.0's may be the exception to the rule, because mine rarely had anything wrong with it as well. I shouldn't have sold it either, but now I have a VR6 :nod:
