AFR & LTFT Help?
So I've been doing some looking around and I've understood the first O2 (upstream) is for A/F and the second O2 (downstream) is essentially for checking if the coverter is working. I've been having a problem with really bad LTFT like down in the -20/-30 percentiles and my car was recently up at the mechanics and he said I was reading 14:1 AFR at WOT I emailed my tuner and he assured me I was not. He sent me a revision tune and I'm still having my problem. So my question comes, will doing the sparkplug non-fouler trick will AFR if I did it to the upstream sensor? In hopes of decreasing LTFT.

Do you know a way I could test for boost leaks without going out and spending $150+ for the smoke / test machine?The 1.4L LUV is extremely sensitive to air leaks. Last year I bought a smoke machine to fix some very small leaks that I couldn't find.
Would have to do some looking in the garage, if I remember right I have a old engine style compressor and I think a newer compressor, but I think I do yes.Do you have an air compressor?
