Mixture codes
Hey guys, I hope this is the right sub forum. Long story short my car was running fine for a while but recently started throwing a 2d2e code but I didn't think much about it at the time as nothing much was caused. I am not getting codes
29E0 29E1 2A2B 2A2C 2D2E The car seems to run fine under full acceleration or crushing but idling it where it has problems as the AFR will jump around at idle from 16-18 before settling back to the 14.7-15.2 range. Also while cruising if I don't hold the pedal more than 20% say I'm just at the 8-12% pedal range I can feel a slight oscillation in the acceleration of that makes sense. I have include a log from last night from 3-6 gear. Nothing crazy as I didn't want to hurt the car if something is wrong. Any inputs would be appreciated. https://datazap.me/u/cordog41/3-6-pull?log=0&data=3-22 |

Looks like you're getting codes for all 4 oxygen sensors. Rock Auto has the cheapest prices on those. Follow Vehicular DIY's tutorial on YouTube for a cheap post cat replacement job.

The problem ended up being a torn a hose to blow off valve. I'm not sure how I missed it because my vacuum was only at -8.7 when it is usually a lot higher at idle.
