check my faq link below.

On reason if overnight bad MPG is a busted Intake manifold gasket.

Did the dealer replace the gasket?

There is a certain torque spec to use not much and the plastic gasket can crack.

IT WAS REPAIRED BY ISUZU, THEY CHECKED RECENTLY FOR ANY LEAKS. THEY ALSO TOLD ME THEY HAVE NEVER HAD ANY PROBLEMS WITH ANY SENDING UNITS OR EVEN HEARING OF IT..:)
