these engines have a distributor that gets wet too easy. driving in water is not recommended meaning no deep puddles...this OPTI distributor has a venting harness. remove the lower vent hose see if water comes out ..if so you will have to replace it. not a fun job.. expensive..engine light flickering on off says miss fires that then says you got a wet distributor at the least...most likely new is required and recommended with all the work to get it out...........

Second vote for an Opti cap and rotor at least. If you are fortunate you can dry out the optical array and clean the interruptor discs. It would be a good odea to verify that the Opti vent system is connected and functional. It consists of a couple vacuum hoses and a check/flow valve. It will greatly extend the life of the system. Only the B and D bodies had the vent system in 1994, but all other LT1s got it in years thereafter.
