if the engine light is on it set a dtc. you need to get it scanned and find out what dtc(s) it has stored.

Don't worry about the O2 sensors yet. Get the codes read at a parts store and find out what has failed. The O2 sensors report a problem. They won't all fail at once. As long as the check engine light is on, you will burn a lot of fuel.

Ok thank you, thinking maybe spark plugs or coil packs but will do thanks.

It could be a half dozen different things. Throwing parts at it shouldn't be your first step. Plugs and coil packs won't hurt but it might be a unnecessary expense at this time.

does it seem like it is misfiring once you get up to speed or doeit go away.

Get the codes and then you can start working from there. Can be many different things.

File exhaust system you will get a check engin light and most of the time you will get a 02 sens failure code most people go to auto zone to see these code which is ok but always look for the others issues

If there is a misfire in your engin you can change your spark plugs first if that does not work the next step would be the coil packs or ignition coils I know this seems to easy but the problem is that when you get a misfire code you go how you take it apart you clean it put it back it works for a few secs you wast your gas go back to autozone check the codes again and it's a misfire on another coil

If your car is shaking once you hit 40 to 50 MPH on the high way you think it's the bearings or your at a red light and you take off and your foot is all the way on the floor and your moving 5MPH then you take off is because your ignition coil is inconsistent some times it work then it stops the best thing to do in this case is change all of them because this can be happening to more then one atanygiven time so if you change one it my be happening to another one at the same time

Ok long story short auto zone sells ignition coils from 30 to 80 each what I do is go to eBay select new and you can get all 8 or 6 for 65
