after you made the changes did you reset the computer? Sounds like you didnt try disconnecting the battery for at least 5 minutes. Could be the computer has to re learn the car now with the new sensors installed.

my brother-in-law was the one that workedon my car.......he said he reset the computer.....does a 98 escort have a relay button? could that be the problem?.thanks for replying back to me ...

When the sensor was replaced was the wire reconnected tightly? If it was left off it would cause this problem.
