Thanks Trav, no K&N here, and I haven't ever had one. You're right though, it is a lot like what another buddy's Taco did with oil on the MAF and a gummed up throttle body from his K&N. I clean both (MAF and TB) every 15K or so, but I'm definitely going to pull them apart and check. I found the resistance specs on the TPS, so I'm going to pull that off and throw the meter on it too.
