Hello Guys, I have a 2007 Dodge Calibre that wouldn't start. The problem,I suspect, stemmed from some tainted fuel that I might have used. Woke up one morning to discover that the car wouldn't start . Managed to do so after a while, but saw the car jerking anytime I stepped on the accelerator. Then it stopped completely . They made me change lambda, cran and cam sensors and battery; still no luck. Want to know whether the 2008 calibre engine would be compatible with my 2007 calibre. Thanks and sorry for the long post.
