Well, My night went to crap, go to the garage to start the car... starts right up and gave me a code P0300 and P0800....

Pull out the scanner and one of my 02's is going bad as its switching slow. Pull the car out to go to work last night, make it a few miles until the car started to shudder and miss real bad, pull into a local gas station saw I was on E put some gas in it and turned it back on.

Still idling rough make a u turn back to the garage and parked the car outside, hooked up the scanner again it came back with p0303 replaced the wire and coil and the engine turned until made a compete halt. Smelling raw gas I pressed the gas to go into unflood mode and it turned again but stopped almost like a lock up. The engine still turns but only for 3 times until it locks up.

Please help

What does all this mean? Stuck injectors?

Ok, Changed the injector on 3, oil and spark plugs.... The car started right up no sounds of ticking coming from the heads only sound close to that was the injectors ticking as they are firing.

Now the car is shooting a code P300, P1380, P0303 checked the spark plug's strap looks like its getting a burn but not fully??? the coil has spark the wire is good. anyone care to point me into the next direction. At this point i'm going to put on a new 02 sensor due to one slowly switching and also leaning to the possibility that I have a bad set of injectors :(

Replace the 02 sensor on the driver side took out similar 3 sparkplug this is what it looks like

*update* Fixed the problem... When replacing the 02 it popped up with a other code that directed right to the source 2 of the spark plugs were cracked and not causing a burn... the spark plug in the picture had a fine line crack not visible to the naked eye, replaced and she runs like a bat out of hell! Only thing left is to lower the gap on the plugs due to it blowing out the spark.
