Hey, well i changed my pcv(non oem) knock sensor, use a TINY bit of throttle body cleaner to clean the MAF, and cleaned the throttle body, use some fuel injection cleaner. And i went from 380KM a tank rougly to 280-300 after doing all this :-\ I am going to get some new plugs from my dealer(1.50 each) and get a oem airfilter, and PCV valve. I will also get some MAF cleaner and spray the sensor very good. Anything else i should look at that is common? Thanks.

 

Also the car has some hesistation on take off, i think its my CV.

How many miles are on this thing. A slow reduction of gas mileage can be a bad o2 sensor, or a clogging cat. Dont forget ignition wires too, since your getting plugs.

 

nipper

has 191,000Miles converted. CAT was replaced at i think 160k(again converted). O2 sesnor, my dad said he changed it, but i don't think so, he assumes he did becasue he replaced the CAT.

 

EDIT: i just asked him again, he said he replaced the o2 sensor when he got a check engine light, but it didn't go away, then he replaced the CAT and the light went away.

 

I should be able to get atleast 450KM a tank CITY correct? people say they average 20miles to the gal, after i converted everything MINIMUM i should get 500KM.

You may need to replace it with a OE sensor. Since your not sure i bet thats part of the problem.

he said he got it from napa, so, ok thanks, ill order one.

Ouch

Busted CV joints don't cause resistance - certainly not enough to cause a gas mileage change.

well, when the car is cold and i make a turn it knocks really loud and you can feel it. Also when i accel the steering wheel turns to the left a bit, not even on hard accel, light, very light. and that CV is a reman, that is OVER 90k. And the boot is partially broken.

 

i think im going to change my diff oil in the front and see if that makes it more smooth.

and replace that cv, gas mileage can go to zero if you break that axle, which sounds like its close.

tommorow i might go to a junk yard and get a CV. Just out of curiousity if the axle did break, would it be RWD?

To a point. I think thats why we can drive our CV joints way beyond what a FWD can can take. Since both the front and rear axles do the work, it puts less stress on any one cv joint.

Today i replaced the air filter, PCV with a OEM, sprayed the MAF(going to spray the O2 later) and did the plugs i got the NGK plugs for $1.50 each, and torqued each down the 16ft-lbs(same with the PCV, i like using a torque wrench lol). Heres pics of my olds plugs and new.

 

Fouled up plugs would definitely cause gas mileage issues.

Please take you OBW to the hospital for a check-up from the plug up STAT.
