I bought this car used about 3 weeks ago. Its running fine. This morning I crank up and the engine light is on. I took it to my local hometown mechanic and he hooked it up to a diagnostic computer. The following error codes were given: PO581, PO593, PO420 and PO113. I am needing to find out exactly what they mean and if hopefully these are easy repairs. Any help would be really appreciated.
