Having two Issues....

[WILLY]

lol,all these posts with no real answers,u live in chicago and i live in michigan,when its this cold outside the vx runs very rich and u will go through fuel like crazy,the brake issue is ur caliper pins are in need of cleaning/replacing with fresh greese,the cold weather makes dry pins keep ur calipers from working properly even worse,i have been through thie same stuff.very simple fix

Rich running is almost always the 02 sensor esp in cold weather. 02 sensor has to get hot to read properly. Otherwise the system will switch to a "open loop" and constantly run as if the motor is very cold and choked. I don't have a VX yet but OBD2 vehicles have 2- 02 sensors one before the catalytic converter and one after. Only the one on the engine side of the cat matters. The rear one just looks to evaluate the cat performance. If the 02 sensor has 3 or 4 wires then it has a heating element in it to get it to the proper temp. They are kinda spendy but so is gas. If you replace it disconnect the battery before you plug it in as they can be sensitive. Freezing brakes issues can sometimes be caused by a low spot in the brake lines. Brake fluid does absorb water. It will collect in a low spot then freeze more easily there blocking the line. The only fix is to bleed all the brakes over and over till all the old fluid is flushed out. Start from the wheel closest to the master cylinder and work out. It's usually easy to see when you start getting the new clean fluid draining. If you've taken a master or wheel cylinder apart and seen pitting there it is from water. Sticky calipers usually cause brake sticking on not off, always causing uneven wear on the pads. Of course it's hard to diagnose from a keyboard your VX but at least both of these solutions are good for the rig either way. Hope this helps.

Did you ever figure out your fuel problem? Mine happens in temp not as cold too. Gonna try the O2 sensor. Ive already replaced fuel filter and plugs.

Was a combination of O2 sensors fuel filter and plugs. Did a full tune up and replaced the O2 sensors and cleaned out the upper smog crap. Ran much better but mine blows oil pretty good so O2 sensors are already shot again as well as my cats I would assume.

thank you. Whats the upper smog crap? Ill replace the O2 sensors

EGR Valve sorry and piping running from it down behind manifold
