so my CEL came on and was throwing P0171, P0300-304 codes. basically meant engine was running lean and multiple random misfires.

basically i figured out the problem, my crankcase vent valve is broken. i plan on just grabbing this part from audi since it doesnt seem to be at any local stores.

my question is how hard is this to install? i can do some DIY stuff but im not a mechanic or anything near that lol i kind of learn as i go
