While driving, I get short hesitations as if I momentarily loose spark or fuel. I replaced the coil, coil wire, plugs, plug wires, distributor pick-up sensor, and fuel filter, with no success. Will continue to troubleshoot but was wondering if anyone in our club had a similar problem. I'm thinking my next step is to drain the fuel tank due to the possibility that I may have water-contaminated fuel (have already tried the fuel additive that is suppose to eliminate water, but don't trust this procedure). Would appreciate any input from our members regarding this problem.
