Hesitating

This is a follow-up to a Q. I submitted a week or so ago re: hesitation on deceleration. I have a 1994 olds 88 royale 3.8l (vin L) with 200k mi. I replaced plugs, wires and one ignition control module (ICM) coil, which had corrosion/rust on the terminal, which caused plug #4 to have buildup on the electrode. The engine ran smoother and quieter, but still had the same hesitation problem: engine starts fine, idles fine and accelerates fine, but when I would let off the gas while driving I would notice a hesitation. The 'check engine' light has not come on during this problem. I was afraid to drive it, so I parked the car and used another vehicle to get around, submitted my problem to this site and got back some good feedback. I decided to see if I could get the car to act up while in park by slowly accelerating the engine to a higher rpm, which it did, but only at high rpm. At first there were 2-4 seconds between hesitations, but when I repeated the procedure 2-3 days later the hesitations occurred at less than one second intervals. During these rpm tests I noticed a coolant leak under the throttle body, which seemed to get worse as the hesitation worsened. So I removed the throttle body and found the throttle body gasket was leaking and was dripping right onto the engine coolant temperature sensor (ECT). So my question now is: Could the coolant leaking onto the ECT be causing the hesitation? If so, and I replace the gasket and dry off the ECT connector, can I expect this to correct the hesitation problem? Should I replace the ECT sensor? Does it need a special socket to remove it? Could it have been damaged by the coolant? Is there anything else in the vicinity I should replace while I've got it all torn apart? Thanks again for your help.
