Like I said, the first thing I'd do if I were you is to change out the O2 sensor just to be on the safe side. i will do As well, looking at the O2 sensor will help determine what is going on by the deposits on your sensor. i want ask you last question: if i disconnect the O2 sensor electric connect...

[quote="PrecisionBoost"]Pictures of a plug might help, also what brand of plug?

Is the car running good, or does it feel different than usual? my plugs look like the one on the left

If it's all spark plugs that are white you may have an issue with the fuel pump not supplying enough pressure/flow or the fuel pressu...

Should the water pump also be replaced, or are they generally good for more miles than that? 3. Is the Daewoo timing belt tool (basically a bi...

The cam gear bolt is a 17mm wrench or socket. A 1/2 ratchet and 17mm 1/2 socket would work great. The oil pan uses silicone not a gasket so repairing that leak would require removing the oil pan, and resealing it. This is actually a job performed in an hr or so (considering the lenghty part is clea...
