Sensors replaced, code cleared and the next day the damn idiot light came back on. With that said the idiot may be me... Tying to save some money I cut the cat off and gutted it out. Broke one stud off the back end and after 2 hours of hammering, chiseling, and cutting I finally got it out, replaced broken stud with a nut and bolt. Put it all back together again, cleared the code and all was good so I thought. Two days later the wife and I went to the casino about a 50 mile trip. Pulled into the parking lot and what do you know the light came back on. Ordered a new cat online from advance auto the next day and of cores I ordered the wrong one. The new cat is 3" in/out and I needed 2.5" in/out. I usually do a lot of research before I buy but being frustrated I just went for it. CAN YOU SAY IDIOT!! I've been researching things and WOW I still don't have a warm and fuzzy on which one to get. Could someone give me a boost... PLEASE!
