Last night I got a code exp113 and said speed was limited to 90 mph this morning I started the car and it said theft problem car may not start and code exp 34. two nights ago the carpet got wet behind the passenger seat on the floorboard. I see no reason the sun roof is not damp or stained and there appears to be no wet carpet on either side by the hump or the door. just in the middle of the floorboard. I disconnected the positive battery cable to see if I could clear the code this morning but it still says code exp 34 and theft warning. Please help me.
