If you changed map sensors and it still throw it... Wiring.

Disable ELD.

Yup. I think your 92 doesn't have provisions for that. That code won't effect you much, but definitely fix the map sensor problem.

Code 20 shouldn't cause that. Map sensor will, obviously.

IT does....JDM more than likely. Fix your MAP sensor issues and codes. The Code 20 will not effect Vtec.
