Check Engine Code T0303
Have been told this is a code for surge engine is firing. The car had not been started for about a week and when started felt like it was firing on only 3 cylinders for about a minute and then smoothed out but the check engine light has stayed on, what is it and what does it mean?
I think you mean "P" as in PO303, correct Oldschool?
If so...
PO303
Cylinder #3 misfire*
Things to look at.....
Ignition coil / Spark plugs / Ignition circuit / Injector / Upstream HO2S / Compression pressure / Timing belt / Crankshaft position sensor / Air intake / Fuel pressure / Crankshaft position sensor circuit and connector / Bad tuning

I had my daughter stop at the local auto parts and they told her the code and she then told me the code, so probably P0303. Well, the matter seems closed at the time, the light went off and has not come back on and the car seems to be fine again.
Don't even get me started on part store guys, the 4th time I went to a part store I got the right power steering hose for a car. Thank goodness they had the old one in their hand or it could have been more.
