On the Mk3's especially if the rear wheels are not being driven at the same speed as the front wheels then the car thinks it has a problem & very quickly switches to limp home mode & reduces power as I found out myself a while ago! On the mk4 it is even worse as if the various sensors don't detect movement as well the car can think it has had a crash & cut everything off!
In short RR'ing a Mk2 can just give an ESP fault if the rear wheels are not spinning but Ford seem to have made the system even more 'clever' in later models................................😡

Another thing from the mk2 that probably affects other marks with similar effects is uneven tyre wear. If the difference between your newest/greatest tread depth tyre to the most worn is sufficient it will trigger the ECU to believe there is a fault.

This also happend when the Goodyear Assimetric tyre was first released. I saw a picture on here with another brand side by sice and you could clearly see that the Goodyear was smaller! OKJ if you replaced all 4, but if you only did 2 some people found that it triggered a fault. Not heard of this recently and the Goodyears are now in their 3rd or 4th generation so I suspect that this situation won't be happening now.
