Hello group I have 3 questions for you guys, I would really appreciate your help, thank you very much in advance.
[Q] 1, I am getting barely 22/mpg (around 245 miles per tank). I would like to improve the fuel economy. The factory specs say that the car will do 25/mpg in the city and 30/mpg in the highway. Is there anything I can do to get better mileage than 22/mpg in a 2.3l 'tang? [Q] 2. The smoke coming out of the exaust pipe smells like the air/fulel mix is a little to rich in gas, should I get a new oxigen sensor? [Q] 3. (Forr computer experts) I scanned the computer codes using a small ACTRON/// scanner and it gave me a code 34 which means EGR Valve Position (EVP) sensor or Pressure Feedback EGR (PFE) sensor: signal voltage out of Self-Test specification limits, or, signal voltage above closed limit during normal engine run operation, or,signal indicatesinsufficient EGR flow. Should I get a new EGR valve?Thanks a bunch again!
