I have searched for a thread and didn't come up with much. I was curious if my o2 sensor needs to be replaced. I think that I get okay gas mileage. 20 MPG city 27 MPG highway. But my car has 124,xxx miles and its all stock. Someone mentioned that I should be getting in the 30's for MPG on the highway. I was shocked.

Also I have noticed that when my engine is cold that it seems to not have a lot of power. It seems to be down on power. But once its warmed up its fine to drive. Sometimes its hard to drive my car when its cold cause there isn't much power to get momentum. I guess. Could that be the DME temp sensor or o2 sensor?

Also could I get the cheap $75 one of Ebay to replace my stock one. it has the stock connector on it.

You can pick up a universal for like $35. Only 3 wires to splice in, very simple. At that price, why not change it if you have doubts?

I think your mileage is fine though.

Does the universal one do just as good a job?

Should be the same as one with a porsche connector as long as the wires are connected right.
