I cleared the CEL code, but the light came back on in 3 days. So, I ordered an O2 Sensor Simulator today. I will post an update when I receive it and get it installed. The cost was $40.00. I hope it works. I really like the extra punch the high flow cat has given me. I don't want to go back to the stock D/P.
BTW, I changed my oil a couple of days ago. I checked my MPG average and it was 35.2 for the last 3000 miles. That is 5.2 higher after all the mods were in place. I am very impressed with the increased performance AND better milage. I probably would get better MPG's, but I am enjoying the HP right now!!!
