I have a code 43 (fuel system) the engine seems to be minorly misfiring especially when not under acceleration (cruising). It seems to me like the fuel injectors could be contaminated. Anyone had a similar issue or know what this is? Would like to get a second opinion before I take the injectors out.
Thanks

Pull the ECU fuse and memory back-up fuse, wait a few minutes, then re-insert them and crank the car. If it seems to run fine... the problem is your O2 sensor. Replace it. If it still runs like crap as before, you will need to see where the problem is. Lack of fuel makes the car misfire... so it could be a clogged fuel pump pick-up, clogged fuel filter, or clogged screens at each fuel injector. Also, a bad fuel pump could be sending lower than normal fuel volume, reducing fuel pressure, and thus... leaning out the engine.
