check engine light with codes p1507 & o0455

[cesart95]

the guy at autozone told me that p1507 was idle air control under speed error and that p0455 was pcm large leak in evaporative emmision control system. Could anybody direct me into how to fix the problem.

The large leak probably means you pulled the gas cap off while the engine was running. This code should clear itself after a few days if that is what happened.

Idle air control valves control your idle, and are a frequent explorer problem. You can remove it and clean it with throttle body cleaner or replace it ( about $50) yourself - its easy to do. Search the web or this site for instructions on cleaning.
