ended up changing both lu an ld switches, and it has been running for a couple weeks now. time will tell, thanks for the input haughtoneer, i was trying to duplicate the error message, and i did remove the top slowdown wire from controller, and try to run the car, it would not get the same error message . the error message was photoswitch error, shorted ld. the mechanic said it just said shorted ld, or shorted lu. when i saw the actual error it had the photoswitch error, shorted ld, that is when i changed both sensors, and all has been good so far.
