ruff running

G.B. 98 XJ

NAXJA Forum User
well, the xj got submerged this spring. I still haven't got it running good. after it sits for a day it starts right up and runs fine. less than five min starts running ruff (like after it warms up).
then it over heats. acts like its starved for fuel.
this is what i've done so far. new(used)ecu, coil, starter, all new fuses, water bottle and hoses.
could the fuel tank gotten water in it?
