Bought my 05 town and country used about a year ago with 62,000 miles on it. two days after buying it the locks quit working, dealership replaced some kind of relay switch, helped for about 2 weeks then they quit working again. my headlights shut off all the time, I've almost wrecked several times because of this. the most recent problem is it started bucking and jerking while driving, gas mileage is horrid ~ getting about 15 miles to 6 gallons of gas, check engine light is on. took it to the garage and the computer says crank shaft/cam shaft sensor. we replaced both sensors and it didn't solve the problem. we've had the fly wheel checked, the timing chain, injector valves, throttle position sensor, fuel pump, computer, and several other things....we have had it to three differnt garages and no one can find the problem. the computer is still saying crank and cam sensors and it won't let anyone even clear the code..any one else have this problem and what was done to fix it?
