Hi ..just registered today .. I like this forum...I got a lot of info.. for my 2009 SXT Dodge Nitro.. My rig is having 41000 km mileage. It is now having and Electronic Throttle control blinking alarm... and seconds later the ESP alarm follow. I did a DIY cleaning of the Throttle body but still the same.. I am planning now to replace the trouble body , the spark plugs are also due for replacement.
