I get 7.0 mpg city, 8.0-8.3 highway!! No matter how i drive( heavy foot on gas pedal or light foot) i am getting almost the same MPG!!!! Ive changed spark plugs! What other things should i check!?? EGR and Oxygen sensor could be the issue?? How can i know if the oxygen sensor needs changing if EGR needs changing?? Wouldnt o2 sensor work bad because EGR is bad?? Please help thanx
No man im not towing anything! Im calculating numbers by both hand and overhead! Dnt know what are the things affecting mpg? Airfilter , sparkplugs changed what else could be the issue? I think its more than one factor!
