Re: 1988 Honda Accord Lxi rev'ing Up and Down

        ECU re-set is done by removing the ECU fuse for ten seconds. The fuse
is in the under hood fuse box.
        See if there is something in the intake screen for the vacuum source in
the big box full of controls on the passenger side of the outer
firewall. (all the vac lines run to it) 
                Good Luck!      bob
