The computer registers two codes, one says the catalitic warmer and the other register multiple missfires. I have done some research on this and I feel that it could be the ERG valve. The car runs kind of rough now and seems to choke from time to time and then starts to run fine for a short while. It has even held up around 4500 rpm before out of no where and then drops back down when I go to idle. That problem has only happened on the interstate at speeds of 65 MPH. what are your thoughts and if it is the ERG valve how difficult is it to fix?
