my 2011 kia is under 70.000 miles. it starts fine from a cold start but after the engine warms up and I drive approx. five miles the engine shuts down and wont start again until I take the spark plugs out and put them back in the plugs are brand new and specified for that engine
my kia rio starts fine from a cold start however when the engine reaches running temp and I drive about five to six miles the engine shuts down. Now if I take the spark plugs out and clean them and replace them ( these are new plugs mind you) the engine starts and I drive five or six miles and the same thing happens
