Well, I threw on a set of berk hfc a little over a month ago I believe and have been loving them. Last night I got a CEL, I figured it were the cats so I went to the dealership to find out. Heh well I think 3 things came up on the scanner. One the guy said had to do with my circuit in the car, basicly its very busy and somethings making it a little frantic, 2nd thing was bank one cat I believe, and 3rd was something with the anti theft system. As he was explaining it I interrupted and told him I had been having weird idle issues where it feels like it wants to stall in traffic. It also doesnt always turn over quickly on first start. He was basicly describing what I was telling him.... soo... Taking it in on monday to get looked at in depth, its an 07 with just about 30k miles on it so he said warranty will take care of it. Anyone seen this before? I took it to the dealer in Heightstown NJ, its an awesome dealership and they seem to be friendly about mods. I'll keep yas updated.

 

huh..its not the cats its some wiring problem or something id say..idk good luck

 

interesting... i hope it isnt anything major.

 

i would put the stock cats back on before taking to the dealer. they will blame the cats for any problems and try not to cover anything.
