Hey guys, I installed a new exhaust system on the charger a few weeks ago, and now the check engine light is on. I cut the suitcase muffler and the rear muffs out and installed the magnaflows. The car sounds awsome, but the light will come on for a few days and then go off for a few. Has anybody had this problem before?
BLUCHARGER
Ok heres the whole story. The light came on 30 miles down the road afterwards. There is no change in performance or gas mileage. I took it to the dealer, they checked the codes and said it was some kind of problem with an o2 sensor, but they did real time monitoring and everything showed norm. They cleared the codes and drove it gave it back and it was fine. A week later it came back on again, I took it back same code this time they were going to replace the o2 sensor but when the tech removed the old one he noticed that the threads in the cat were crossthreaded from the factory. So now they had to order the cat assembly from mich. and it wont be here until tues or wed. Anybody else gone through this before?
