Low idle after driving for a certain amount of time... Starts good/okay then when I stop the check engine light comes on... I lived in Washington and it ran great now I live in Arizona and it runs crappy... Any suggestions on what to do??? I got my entire engine replaced in 2009 and transmition in 2010... Already had to carborators rebuilt... Never been in an accident!!! People say emisions have part of the problem... Washington is not as strict as Arizona with their air quality control on cars... I need to get something done asap... Do you know anyone in the Phoenix area that is great with older cars like this one??? Thanks
