Volvo 1988 740 GLE Low gas mileage.
I have a 1988 Volvo 740 GLE Wagon. It runs very rich. It does something
like 18mpg or so in the city and around 23mpg or so on the highway. I changed the O2 sensor, the spark plugs are relatively new, the gas pressure regulator, the fuel filter. I have tried additives to clean injector but all this just went in vein. Does anyone have any clues as what to investigate? What might be the problem? I like the car very much and hope that I can drive more often but I only try to take it in longer trips because of its bad fuel economy. The car has 150Kmiles on it. Any help will be very much appreciated. |
