My Check engine light comes on when im doing about 70-80Mph... 1.Why is this 2. What is causing it 3.How do i get the dam thing to go out

I have got a fault code out of it and it says that its my Lamber sensor, but that seems to be all ok as i have swapped it with another one.

Any ideas Please!!!!!!!

We can't answer any of these questions without knowing basics like what model year you're running. Does the CEL illuminate at 70-80 irrespective of the gear you're in, or does it only happen when you're accelerating hard, what?

If you're certain that the error code refers to the lambda sensor, and also that another one does the same thing, the likeliest cause is probably a wiring fault between the sensor and ECU. However, this is purely an educated guess and there are any number of possible causes.

In these circumstances you are probably better off having your car looked at by a Select Monitor or DeltaDash, as these (DD especially) should be able to pinpoint any anomalies in the readings.
