We have a 1999 saturn SL1. The check engine light came on. We took it to autozone and it showed a p0303 code. We changed the spark plugs and wires, but it did not fix it. It has been running a little rough.

Any suggestions

So is the miss a constant one?

I am going to change my mind and say yes. We just changed fuel injector #3, but that did not make a difference. Still missing.

Let's do this while the engine is idling remove the number 3 spark plug and see if the miss get's worse. If it doesn't then the number 3 isn't running at all. Be careful not to shock yourself. Let me know what you find.
