I'm guessing loose connectors.
Loose connectors? O2 sensor connector?
Truthfully it could be anything with that many codes, but normally it's something that would cause all of them at the same time, and that's usually something like a loose connector somewhere. Some diagnostic that they all share in common. I don't know enough about it to say which connector or where, but your problem is either very simple (connector) or incredibly complex (four very different codes).
Do you have any modifications? If so list them in the order they were installed. What's the thing you did most recently to the car?
Ok. Haven't done anything to the car in years. Last 2 months been driving it 100 miles a day all highway. Just checked my spark plugs n ignition coils n it's covered in oil. Mainly 1 n 4 starting from left. Advance auto dude said I definitle change valve cover seals. Ignition coils also messed up. On the ones with oil the part that touches the spark plug its seperated. Planning to find ignition coil n the then changing out spark plugs, valve cover seals mainly spark plug seals but gonna change all. What cha think? N is removing valve cover pretty simple? Is there a DIY?
Removing the valve cover is super simple. Remember to scoop up a new valve cover gasket from a stealership before putting it all back together.
It sounds good to me but I'd be lying if I said I ever got elbows deep into my EP's engine. I'm hoping some more mechanically-minded people will show up in your thread soon.
Changed out valve cover seals n is running better but still sputter when I do a rolling yield in 2nd gear. Sputters to a few sputter then it's ok again. CEL is still on but it's only throwing upstream 02 sensor code. WTF. Anyone ever encounter this problem?!!!!!!! Help my baby is sick!!!!
