decreasing gas milage
when i first started driving my cj a lot(a month ago) i got 14.9 mpg regularly for probably 3-4 tanks. all of a sudden, it went down to 12.3, again for a couple of tanks. when i calculated the last time(day before yesterday) it was down to 11.9. What is happening????? what can i do to increase power/milaege? power b'cuz it seems to have an extreme lack thereof. the jeep dosent smoke, but there is a slight gas smell which gets annoying. i was going to put a cherry bomb on to hopefully reduce backpressure, but it was too long to fit without changing a lot. help !!
