Could be one of a few things,
but firstly the running at 40mph is a safety feature to stop you damaging the engine.
I would guess low oil level, or blocked oil filter.
Does it run at a higher temp. when doing 70 mph for a while, or is it running warmer than normal, that is an indicator of low oil level.
I hope this helps

    Did not mention if petrol or diesel??
    If diesel then could be a fuel problem or the EDC (electronic diesel control) detecting a leak or blockage in filter or even moisture in the diesel.
    I hope this helps

If 360 km per hour is equal to 40 miles per hour, please show me how to calculate using formular


360 km/hr is NOT 40 miles/hr.
1 mile is about 1.6 km
To go from km to miles, multiply by 0.62
To go from miles to km, multiply by 1.6

Kilometers per hour to Miles per hour

98 FORD EXPEDITION ACCELERATION ISSUES


Do you have a check engine light blinking when this problem occurs? I assume you do because if it is missing and sputtering like you say the engine control computer would detect that and turn on the check engine light. Next step is to have the systems fault codes read through the diagnostic port under the dash in front of the driver, Autozone and others does this test for free.

I put 2,720.00 worth of work into my 97 Pontiac grand am. Engine light is flashing the car sputters and might get up to 40 mile per hour I took it out on the road again and got it up to 75 mile per hour...


Sounds like who ever did the work on your car needs to go back and check the plug wires to see if they are going to the right plugs. and check the fuel filter, and fuel pump pressure. I would also check the Catalytic Converter to see if it is stopped up, if so replace it. Check the throttle position sensor with an ohm meter, if bad replace it. Check the oxygen sensors as well. I am running out of Ideas, so I hope this helps.

Car wont pass 40 miles per hour


If the check engine light does not come on, runs ok at low engine load and low speeds, but falls on its face under heavy load and faster road speeds, I would have to say that the fuel filter is the most common culprit of your problem. Generally, it needs to be replaced at least every 30,000 miles, but that is just a rule of thumb. They can be clogged at any mileage, causing fuel flow to be restricted to the engine.
