random stalling
 

:confused:My 04 freestar has 105000 miles on it and had the 100000 mile tune-up. now at 105000 it is starting to randomly buck while driving like it has water in the fuel. Diagnosed as computer gone bad. Changed coil and found different plugs not firing than with origional coil. Computer sent out for refurbish/rebuild. Finding that it now is staling now more frequently than before repair?
