Some of you might remember my thread about my 99 chev sloppy shifts and sloppy idle.
Long story short I went mudding awhile ago and bottm on a rock which cracked the exhaust flange right before a o2 sensor. Which tripped a bunch of random bs. Horrible idle, worse shifts , bag mpg etc.
So I went in and welded it, the rpm is steady 600 and shifts like a dream. 100%
Assuming now it was cracked all along. And just got worse to where I had to fix a simple exhaust leak which did WONDERS
So freaking happy atm . I can enjoy driving it again wooo
