    Hi, I have a 1993 Ford Escort LX 1.9L. It's a great car and has no problems except for one thing. Whenever I try to accelerate it does fine unless I'm demanding some power from the engine, in which case, I actually lose power and and it sounds almost like a piston stops firing or it's starved. My aunt works for with auto parts and said it might be my fuel pressure regulator. I replaced the fuel filter, plugs, etc. but haven't replaced the regulator yet. Before I did this I wanted to see if anyone might know what this problem is.

    Whenever it acts starved, I have to down shift otherwise I can't make it up big hills. My parents have a hybrid with a 1.6L engine and a heavier car and it has more pickup and go than my 1.9L.

    I've been stumped with this mystery for quite awhile. Any help would be greatly appreciated.

    You might change your fuel filter it you haven't already. Mine did the same thing when it clogged up.

    Yeah, I changed the fuel filter already. It helped slightly, but didn't make very much difference. When the engine chugs, it audibly changes. Instead of the constant pur, it goes ka ... ka ... ka ... ka ... ka with distinct spaces between the chugs.

    check ur spark plugs and ur injectors...dont hear much about the regulators going out. run some fuel system cleaner through or just higher octane gas and see if it starts to get any better..

    you might also check the wiring harness running up to the coil pack and make sure that the wires are in good shape.

    Just wondering does this problem seem to happen most at certain RPMs or throttle positions? Is your car a manual? Does it behave the same way in all the different gears?

    To answer Macgyver4's questions:

    -It happens at any rpm, whenever I'm demanding acceleration or pushing the gas down to go up a hill and maintain speed.

    -My car is a 5 speed manual.
    The clutch is new and is properly adjusted.

    -It happens in any of the gears. Even in first gear if I don't rev the engine pretty high to get going. (higher than normal, or other escorts I've driven)

    Could there be a bad spot on the throttle position sensor?

    Also have you checked your cars computer for codes?

    well other then the car being underpowered for the gear ratios so you have to downshift for many things, have you replaced the plug wires?

    if downshifting helps, then i doubt its the fuel pump. the fuel pump will cause loss of power throughout. the plug wires can miss under load but when rpms jump up higher, it can sometimes go away.
