Anyone ever come across this code? Couple weeks ago i did the coil workover , changed plugs, air filter, coolant flush. Cleared the codes stored in the comp. Drove it home got half way there and this code went off. I cleared it again, tried a water trick my buddy knew on how to clean the cats a little. Drove home and once again there it went. This time i took it to the dealer. I was told by the dealership that the cats are under warranty until 85000 miles. So i figured what the hell , let them figure it out , rather than me pull my hair out. Any ideas? Oh, the reason i did the coil workover is because i was driving down the jersey shore and got half way to capemay and it started missing, so i ran the car on 3 maybe 4 cylinders for about 100 miles. But since i did the tune up the thing runs like a runaway slave LOL.....

LaPoint. Go talk to Nicole in the service Dept. See if Tracy has time to do it, TDUB. Chances are Tracy won't do it though. He's a MECHANIC, not a grease monkey. But he's the only mechanic that touches my vehicles.
