I am having a serious sputtering problem! It started recently and now it is extremely bad! I just changed out my plug wires and cap and rotor because I was also having a misfire issue. That seems to be gone now that I have changed the plug wires and cap/rotor. My plugs are only a few months old. I do not know what else to change besides the fuel filter and O2 sensors. I also cleaned my K&N filter as well and checked my mass air meter. It was clean.
What else can I do, change, or check? My car has never ran this bad! Please help!

I have a small code scanner but I can not find the small book that has the instructions and codes.

Ok, with the key forward and car off, I got code 66 and 91. The car runs not to bad until it reaches operating temp. Then the check engine light comes on and the car begins to sputter and jerk and kick! I changed the temp cool sensor, the one next to the distributor cap, not the one next to the injector. I am wondering if the one next to the injector is part of my problem?

I thought that the coolant temp sesonsor effects the emissions? Which is why the check engine light comes on once the car is at operating temp. I also thought that a bad temp sensor can give a code reading indicating that the O2 sensors are bad?
Is there anything I can do or check as far as disconnect while the car is running to try and eliminate things?
