The engine code always through out the error code 0441 but it ran fine. Recently. my truck has been idling really low-sputters and shuts off at red lights or really low RPM's. I took it to a mechanic a cousin of mine knows and the some biatch enigne light TURNS OFF ON THE WAY THERE!! SI get there, tell him what's happening and he connects it to a little computer and says it's not throwing out codes I can't do anything. I don't know what to do. It's still sputtering and the engine light turned BACK on a couple days later... Anyone know what's wrong???
