We have a 1996 Sunfire GT and the ETS light & Check engine light comes on the PO said it was because the computer is wet (the one in the Front fender) Has anyone heard of this???

can't say what the check engine light is about, but I had a problem with my ETS, It would not turn on or off. It turned out to be the actual wireing in the stickshift. The wires have a cheap plastic shield that after so many years of usage it rubbed against metal and other things. It nicked the wires inside. Take a look at that before you do anything else.
