Yeah I’m up to about 400 now, O2 sensors next.
Wow, I guess I got lucky. I just replaced my fuel filter and fixed a busted vacuum line and I easily double my fuel mileage!
Id love to know which lines u replaced, ive done about 5, my fuel filter, air filter, cleaned my maf. And im still only gettin like 240km to a tank, I unplugged my O2 sensor to see if thats screwed, but i just filled up so i dont know yet. Im goin nutz here.
I never actually replaced any lines. I just started looking around at all my vacuum lines and there was one that ran up underneath the throttle body that for some reason had a tee in it. I replaced the tee with just a straight connector and now I have perfect Idle and better mileage.
