I just got done installing my digital guage, it was a pain in the ass until I realised there was a screw next to the air vent.... Anywho, after installation, everything is working fine, except the engine check light is on. When I press and hold onto the gas a lil bit, it goes off, but when I let go of the gas, it comes back on. Does anyone know what's goin on? Also my mile guage isn't being lit up either. Maybe I got one that's not working too well? I hooked the speed cable, and the two other plugs into the dash cluster, and plugged my rear window defroster, clock, and oscilating fan plug.
