My caravan has been running iregular sputertting and running rough part time I have replaced the computer and it ran well for about three week. Then the same problem running rough sometimes then good sometims. I have found a leak in the radiator and fixed that problem but the van still runs rough also the map sensor code keeps coming up and I have replaced the sensor. can anyone help.

 

I could help you but it would need to be in person. id connect a scanner to your vehicle, read the data for the sensors that could be causing your problem then i'd use a factory service manual to pinpoint the problem, test the systems causing the problem, make any needed repairs and then verify it's fixed.

other than doing this type of testing and diagnostics it's all just a guess as to what the problem is. you need reference materials, testing equipment to see whats up.
