luckily I bought mine from a dealership and they had to fix it to pass emissions to get it registered. what they replaced was: both maf's, timing gear, timing chain, syncronized the throttle bodies, a couple of vacuum hoses, two O2 sensors. plus I had a C service performed on the car.. and it just barely passed......
Hopefully your car is mechanically sounds and serviced regularly because if you don't keep up with them more things go bad and snowball.. good luck and if u have any ?s about emissions feel free to pm me.. |
Ya, I agree with you. 600s are a biznatch to get running clean. It's never going to pass emissions test with flying colors. Heck, they BARELY passed when brand-new, so now that the cats are 10+ years old you can be certain the situation hasn't gotten any better with age.
Mine always smells rich at idle, etc. Luckily I live in FL, where we don't have to pass emissions. I am still going to clean out the MAFs soon and will have the dealer replace all my pre-cat O2 sensors next time I'm in. That should solve my problems. Probably still wouldn't pass emissions if I lived in a state that required an inspection, though.
Two independent MAF's, two independent throttle-bodies, etc. etc. is just a lot to keep in sync.
