Having a similar problem with my Disco. Talked to a couple guys I know who done a lot of work on them and you might check the O2 sensors and/or the spark plugs. My Disco kinda pulses during acceleration especially when you first crank up. When it warms up is smooths out. If that is what you mean by running rough. If your more chugging like the car just doesn't got it, it more likely a fuel flow issue.
Last thing cause it would be the most expensive. Your computer could be crapping out. The Disco doesn't have a mechanical distibutor. It is all done by computer and that could going.
Hope this gets you started.

96 dodge ram sputters and dies whem you give it gas


you need to check fuel pressure with a pressure gauge to see if its within specs.it should be around 35psi and no lower then about 32psi.your problem sounds like a fuel pressure problem and the pump should be changed as well as the filter, but check to make sure the fuel filter is not plugged as this can also cause a pressure problem.

Sounds like 2nd gear in the transmission is slipping. Cars usually shift at 15-20 mph from first to 2nd. First check the trans fluid.

Check the radiator fluid level and top up if needed.
Check the gearbox oil level and for signs of discolouration. Replace if needed.

Try taking the positive battery cable loose for 2 or 3 minutes, this will allow the computer to reset. You probably will still have a check engine light but should run until you can turn it off.

Check trans light comes on after a few blocks of driving


Go buy the repair manual for vehicle (about 20 bucks) AND a code reader.(between 50 and 300 bucks. Both specific to your vehicle AND vehicle year. Million reasons for check engine light - but that light is basically saying, "I'm seeing something wrong, so check my vehicle computer for what I'm seeing" and the fact that it goes away or may go away just says the problem may be intermittent or keeps being cleared for some reason, either the problem fixes itself or the computer clears code for some reason, probably the former.
