    Will idle but not drivable...

    I have a '98 Catera with around 60k miles and I can't figure out this issue. About 12 months ago the car died and I successfully determined it was a bad coil. About 4 months later it started to act up again but with slightly different issues. At first you couldn't notice a problem until you slowed down to a stop sign. It got slightly worse then suddenly it would only idle and sputter and run very rough when hitting the accelerator.

    It does throw CEL codes... PO300, PO303, PO305, PO131, PO151. Things I have changed... in order...
    - 2 new coils
    - New O2 sensors
    - New sparkplug wires
    - New fuel filter
    - New Crankshaft Sensor

    It seems like the spark - fuel ratios are messed up and probably because one of the input sensors is bad. The lean codes on the 02 sensors are likely because of messed up spark - fuel ratios. It starts rough and will idle on its own but its very undrivable after that. I thought I would post this before I change every sensor on the car. I was going to target the Camshaft or Throttle position sensor next?

    Any experts with the same symptoms?

    Thanks
