Mileage? When you start to run into many codes causing CEL it could be faulty ECU due to oil/water contamination. It's a known issue one of the sensors (forgot which one) can leak oil, and that oil can seep in all the way to the ECU. Probably not your problem though... Replace spark plugs first if your around or above 100k miles. Coil packs don't tend to go bad. Especially all of them... Oxygen sensors don't tend to go bad either although they certainly can. You running premium unleaded or regular?

In that case start with just the oxygen sensors... Have you cleared the codes to see if they return?

the codes are been cleared, one think that i notice its the spark plugs and air filters are the same as manufacturer, means this car with 60k it not been made any maintenance before, do you think could be for this reason the codes shows?? before i cleared the codes, the scan show me 4 codes, P0173 P0170 and repeat it twice, do you know why??

thanks
