sounds like my car before, something is causing the engine to think its on a load. it took the mechanics 3 hours to figure out.

coolant temp should be in front of the #1 intake runner, and air temp is IN the #5 intake runner

thats not even funny bro... being on post approval sucks.

But yea.. its a common problem with those big doofy K&N filters... your radiator fan causes turbulence in the MAF sensor and screws up the readings
