hey whats up people? i bought a code reader for my car and its giving me the codes 31 and 85. Has anybody dealt with these codes before and if so could you point me in the right direction. i have taken off all smog and ac equipment, i used a EGR delete plate as well but i haven't put in a dummy plug yet, that was about 2years ago so im thinking that is what Code 31 is. The car also just start having the idle bounce around between 750 and 1200, im hoping by fixing these codes that it will fix this problem. Any help would be greatly appreciated
