I have a 1998 discovery that has a sporadic missfire. some times you can drive a few days with no problems other times just 15 mins. But it only miss fires at running temp and will not go over 1500 rpms. I have replaced all 4 o2 sensors and the crankshaft sensor. It has been to a couple of shops for diagnostics and they can not get their computers to communicate with mine.any assistance would be appreciated.

Without knowing if it has any check engine codes, I would ask, is everything stock, normal dry air filter or do you have a oiled airfilter?
everything is stock dry air filter the mechanic said there are codes they just cant be retrieved do to communication issues

This is normally caused by corrosion at the ECU connections. Not a good sign, but can be fixed.
