After P0440 code started showing we replaced gas cap and fuel filler neck, which was badly corroded,
and fuel pump. Code was going on and off at times but mostly on. Also actually flashing when hard acceleration up hills. Then Code was popping on and off before new filler neck install.
After all the repairs we removed neg battery cable to hopefully reset computer, but code remains on.
Can you please give advice?
have the same problem?
