i've been using a analog volt meter to extract the codes from a 87 lx ...and have been consistently getting a code 74...does anyone know what this is ????????..there is no listing for any such code that i have come across yet...
i've also been getting a code 32 for the EGR but have replaced the egr valve and/electronic switch, and the egr solenoids...any ideas ????both codes are KOER....

Code 74 KOER is "Brake on/off ground circuit fault". Code 32 KOER is "Canister or EGR valve control system" You may have no vacuum (canister) that is why you are getting EGR code.
