check engine light

[jdn40]

wasnt sure where to put this one , but.... check engine light comes on when the RPM's get up around shifting range . when i let off the gas to shift , or just let off the gas , the light goes out . it comes back on when the RPM's go back up . thinking vacume leak ? it runs fine just trying to figure out why it would do that . i just put in a new computer and it runs great .

i would first check back of the dash clean connectors and dielectric grease them glad pc fixed it sounded like it was ignition module inside it

already did that . im also having a problem with the speedometer . it stopped working some time back . i replaced the housing , speedo head and the sensor and even the gear . was hoping the computer would fix it but no luck . not sure where else to look . also the ribbon in the housing looks fine . all other lights and tach work .
