    Anyone ever have problems loosing bus communication while driving?? Car still runs fine but all the gauges die. I shut the car off, and restart it and everything comes back. The only pcode which can't be cleared is p0030 (O2 heater circuit). The car does run like crap in the morning so I'm thinking this may be true.

    Any ideas would greatly be appreciated

    I guess I left the abs part out as I didn't think it was relevant. I've had abs/trac control lights on since I put the engine and trans back in. I just figured that was from getting water in the module when I powerwashed the engine bay with the engine and trans out.

    I would figure out why you are getting and abs/tcs light, it could be wires, sensors or the bcm itself.
