All out OBS.
Haha yeah I got the joke a few days late. As far as the CTS, it and everything else is brand new, EXCEPT the MAP sensor, and if I remember right, it was throwing readings that didn't make sense. I'm gonna see if I can snag one and a ground strap from the junkyard when I get back in town on Tuesday.
Lol, it was a bad joke regardless. Definitely try the MAP Sensor. I remember a looong while ago, somebody had dropped the air cleaner lid down and cracked the MAP sensor 'box'.. was that you?
