Everything has been fine up untill today...I crank my car up, let it warm up..back out of my garage and all of a sudden check engine light comes on. So i pull back into the garage and i hit the little switch that shoots the code on the place racing harness and the check enigne light blinks 1 long time then shuts off then blinks 1 more long time...so from what i have gathered from my research on trying to read codes...i came up with code 20..so i look in my Helms manual it says Electrical Load Detector (ELD) Is that right????? looks like my research on trying to read codes is no good Please help
