I have an 07 Dodge nitro. Has ran fine since we have had it but slowly started to have issues. First off the water pump developed a leak. No big deal. Easy fix. Then while driving the cab lights would flash every once in a while. Then the power locks stopped working. The lock on the key and the switches inside. Only unlocked manually. Other day while driving down the road it just shut off. Cranks quite awhile before starting back up and will only run if I give it more then half throttle. If I let off it just dies. Smells really rich after it dies as well. Can anyone help? Thank you.
