So about a month and a half ago my car's service engine light came on (orange wrench) I've been trying to get my car to do this again and throw the codes because I cleared them the only way to get it to stop hesitating to go was to shut it off and clear it with my little OBDII tester or just shut it off and turn it back on mind you this happened once again about a day and a half ago I was running 87-90 and it done it I was able to limp it to a Wal-Mart parking lot but it was scary to listen...
