Well ordered the new coupler last night and went to Loews today after work and bought one form the pluming department in the meantime till it arrives, I also cut the heat shield about a third of a inch off the top (there was nothing to cut off the bottom) put it all back together and just got home from a 20minute drive....
NO FREAKING ERROR CODES WHAT SO EVER!!! I'm a little optimistic that that was my issue. The car drive good and I got up on it when I could and the wrench light never came back on at the red lights. There is still a knocking sound when I first turn the AC on but that stops after a few seconds. I'm still going to take it somewhere to have them check it out just too hear someone say it's all good but it might have just been the stock coupler and exhaust issues. Now one the next thing I want to replace the break pads and rotors they scrape too much for my liking. You guys think the stock breaks are good or should I look into upgrading?
