    If i don't figure this out soon ima axplode

    My car, boggs out at low rpms. So far i have

    -New Coil
    -New Plugs
    -New Pressure Reg
    -New Coolent Temp Sensor
    -New o2 Senser
    -Tested the Fuel Pumps
    -New Fuel Filter
    -New ICV
    -Run it with a different comp

    I think that is all. It seems to be fine in the morning when i go to work, but by the time i get there it seems to start, then runs like that all day. When i walk on it from the start, it kinda boggs up to 2700prm, the lights up and takes off, and is long as i run each gear above that it seems to run fine. I have been chasing this problem all summer, and am ready to sell my car if i don't find it soon. SOMEONE PLEASE HELP :?

    Is it just sorta general bogging, or does it run like 1 or 2 of the cylinders are not firing?
    I've had head gasket leaks on some cars that behaved something like this.
    Is your coolant level staying steady?
    I'd pull the plugs and check the condition of each.

    Also, you might want to mention which type of motor you have.

      it's more of a hesitation boggy feeling, there are no leaks, and gone through the intake thouroghly to try and find any vacuum leaks and there is nothing

      the car is a 86 325

        I'd check the plugs for their condition.. one thing you haven't listed is the AFM and associated air temperature sensor, that might be the culprit. If you have access to another car with the same engine and AFM, try a direct swap.

          unplug your 02 sensor for a while and see if that helps... me and another guy on here have had this same problem for quite a while and have narrowed it down to the 02 sensor wires being chaffed somewhere's along the way to the computer

          hope that helps it solved my problem, well put a bandaid over it, it is slightly harder on gas but still gets 600km's to a tank so i'm happy

            Just fixed mine wth similar sounding problem. I replaced both fuel pumps(2) and the fuel pressure regulator . These are items that have a 100,000 mile life to them. If you have more than that they need to be replaced regardless.
            After replacing them you can then figure out how to fine tune your fuel injection system.
            My fuel pump problem was intermittant, as they often are , making diagnosis very difficult.
