Hey everybody . I was out messsing around as usual and got into a confrontation with a cummins with stacks on it , I ultimatley won the negotiation @ about 120 but my check engine light came on and the truck would barely run. I got it home and the code said 0087( I think),anyway I was nervous so i just cleared it and drove it to see if it would run and it did but I did not get on the throttle much.My question is what do you guy's think happened and did I screw it up bad or did I get off lucky
