Thread: Couple weird issues

Just a question... What made you change your O2 sensor in the first place? You neglect to mention that.
Also, I really don't think an exhaust leak would cause the issue you describe, don't quote me though... But I agree maybe a broken vac line somewhere as that seems similar to what you are saying.

Just my $.02

I forgot to mention earlier that i did try running it with the maf unhooked and it only got worse so i plugged it back in and the reason i changed the o2 was because i kept throwing a po135, po141, and p1133. Has not thrown any codes at all since i changed the o2. and about the vac lines, ive checked them all and they all seem good and they are all brand new. i thought if you saw positive ltft it was usually vac leak and negative ltft means exhaust leak. i dont see any positive numbers since new o2, all negative.
