One problem related to service engine light on has been reported for the 2005 Dodge Dakota. The most recently reported issues are listed below.
During stops the rpms on my 2005 Dakota will go erratic. The rpms will go from a few hundred to over 3000. The vehicle will stall and has to be put into park and restarted. No service engine light will ever come on. I have had it at the dealership were I purchased the vehicle 3 time for this problem and they can find nothing wrong with the it. The last time I took it in to have this problem it stalled in traffic that same day I was told they could not find any problem with my truck. This is just one of several issues I have had with this truck that the dealership could not find a problem.
