Pontiac Repair: 96 Bonniville SEEI Ride control, bonniville, light flashes

Question
My wife spilled coffee in the push button portion of the console that houses the performance/touring ride, performance/touring shift and traction control on/off buttons. I rem/cleaned and reinstaled the entire assy.  Electrically all is well it seems. It worked for several mo but now intermittedly upon accelleration the chk/eng light flashes and traction control turns off. Engine stutters once or twice.  Holding down on trac/control button for half a minute clears prob.  Love car- 21mpg! 156K Belts, brakes, tires only repairs.  HELP

Could this be related to supercharger problem I wrote about earlier?  I found several cracked and crumbled hoses under engine shroud.  Yes car runs still.  Thanks again!

Answer
Hi, need when the engine light comes on it will set a code, if you can get this code it would help in finding the porblem, the problem is in a sensor or a relay just not sure witch one. I don't thank that the cracked lines would cause this because it don't do all the time.
