Is there anymore specific info that you can give? Like...


Does it seem to be over cooling? Possibly have a removed or aftermarket thermostat?
Are there strong or at least noticable gas ordors after a trip?
What, if any modifications have been done to it?
How new are the O2 sensors?
What was the initial reason it was taken in for repair?
When does mileage seem to suffer the most?Come back with some more specific info and youll be able to ask better questions.
