check engine light on for 2001 corolla

[gvazz]

Guys, I am also seeing the same problem. Initially, it appeared when i heard knocking engine sound yesterday. Then i immediately checked the engine oil, It was way below the lower mark. I will have to take it to a mechanic to find out the cause of oil leakage or burning. But, today i put the oil and had the level in between the markers on dip stick. After starting the engine, i am still seeing the Engine Light. Although i didn't hear any knocking noise like the other day, i am still suspecting something is wrong. Is it possible that, the Engine light was not lit when the oil level was low for sometime and since i was running at that level, the engine is badly screwedup. Because i don't seem to see the warning light few days back. OR is it possible that since i filled the oil half way between the marks, the Engine Light is still on. I am a novice, so please bear with me for all stupid questions i may be asking. Anyway, i am going to take the car to the mechanic (Jiffy Lube) and have it checked. I will also get the oil and filter change done, as i have driven 6000 miles since my last change. Also, is a mechanic like JiffyLube is OK to deal with the Engine Light problems or should i have to go to any particular mechanic who is an expert in these. I would appreciate your replies to my queries. thanks.
