Im so relieved that this VX has passed smog. I was able to get my new plates finally, because the personalized ones that it came with needed to go!
Here's my readings:
Now the only problem i'm having is that im still getting between 25-28 mpg.
Compression was check on all 4 cylinders and they were all good. EGR was good. I had a new cat installed below the stock cat, so I'm running with 2 cats right now. At first the NO was high, so it was recommended to put a new cat in. After it was installed, the car passed. What can I do to get better MPG?
You already know this, but I just want to confirm that something is very wrong.
There are about 26 VXs in the garage here, with gaslogs. In aggregate, hundreds of fills have been reported. The number of times anyone has ever reported a fill under 30 mpg is very close to zero. There is one car that reported these two fills: 28.98, 26.57. Another car reported this fill: 29.22. I can't find any other VX fills under 30 mpg. So your situation is pretty unusual.
Typical overall mpg, taking into account all the VX gaslogs here, is about 45 mpg.
There are all sorts of pretty obvious things to check, but I have a feeling that it's probably a combination of factors. I'm also optimistic that the problems will be easy to fix.
you DO have multiple cat converters now. maybe the 1st one was buggered and you ought to have replaced it instead of adding to it. would go along with fixing your trouble simply by adding a cat.
