I drive my Crossfire "broken" just about everyday and have been for a long time. For some reason it has a problem fouling out the Mass Airflow Sensor, even with a brand new SLK320 airbox and filters. I've bought several of them and they usually go bad within the first day of installing them. The dealerships say they can't warranty them unless I spend the big bucks for them to install it them self. Even though they scan my car and say it's the MAF still, I think it has to be something else. Maybe an o2 sensor or a fuel problem. The car gets real sluggish as soon as it warms up, and surges real bad and you have to be heavy on the gas to get around. Driving it lightly it only gets about 240 miles to a dead empty tank which compared to people on here seems low. Oddly enough when I feel the tank all the way up it drives much better. Maybe the fuel pump is going. I do love the car, but I admit I've tried trading it in because it's been a nightmare for me, but the resale has dropped so much I can't even get rid of it. I just wish mine was problem free like everyone elses...
