13.8 would be about right if you are making short trips, even if part of the trip is at freeway speeds. Also, if the MPG has been reset fairly recently, the average will appear lower until you get more miles built up for reference.kieblerh said:I have a 89 Biarritz and my car computer says i get 13.8mpg, alot of people on here say they get like 20mpg....what can i do to get that up?
I must respectfully disagree with you on this. While it is true that the EGR tubes remain unclogged in these models the throttle body does still benefit greatly from the cleaning process described on this site. I can attest to that personally. After cleaning mine I noticed a distinct difference and improvement in engine operation.Edahall said:Unlike the 1990 and newer engines with multi port injection, the EGR tubes and throttle body should not need cleaning. On these engines, two injectors squirt fuel down the throttle body which ends up self cleaning things.
I'm not sure if there are posts remaining so here goes;Edahall said:Well, you might be correct on the fact that cleaning the throttle body benefits greatly. I did a search but I'm not sure what cleaning process you're using. Could you provide some links or briefly describe the process? I would like to try it out and it'll be a good test since my engine has 210k miles and the throttle body has never been touched.
