engine CEL help
Hi guys, I was wondering if you could help out with a couple CEL codes Im getting? "Mixture deviation", cylinders 1-6, and "Oxygen-sensor control limit", cylinders 1-6.
I've read this is mostly intake related, I have a new HFM, and have smoke tested the vacuum system (fixed a few hoses), but not the intake manifold. These problems started a few weeks after my new engine install, I'm guessing hardware issue or sensor. When driving it hesitates, and is obvious something is not right. When I use my second tune it revs at idol and stalls out when not in gear. I know these are classic signs of extra air past the HFM, just run out of places to look. Was wondering if you guys may have some advice?
