Just had header, hi flow cat, and exhaust done and can't get my engine light off. Had it done @ ASAA Racing in h-town and now they're saying i'm going to have to replace my OBDII with an OBDI. Is there any other way to take care of my sensor problem and if not will replacing the OBD really help or just give me more problems??

 

What code is the CEL throwing?

 

You don't need to convert to obd1. Go to autozone and have them run a test and tell you what code it is throwing. They do it for free.
