Ya I think I'll give that a shot. Thanks!

And no, I don't have the AFR calibrator (which in my case would've been the O2 sensor calibrator).

This is definitely something new and weird to me. The only things I can think of are faulty MAF sensor or front O2 sensor, but that's a real shot in the dark. Plus, no error codes. <img src="/forums/images/graemlins/barf.gif" alt="" />
