Ok so I have read many posts on this and cannot track this down. Went through a car wash with underbody flush, came out and car was running rough. Thought it would dry out and be better, no luck. Check engine came on solid - codes 300, 301, 302, 304. After reading on here, I replaced all spark plugs and ignition coils on 2 and 4. Ran great for two weeks (about 500 miles) then rough idle came back and it has no power but will cruise around 70 as long as I don't have to pass anyone and ease my way up to that speed. Sounds like I am not getting any turbo boost, flashing check engine now with codes 300, 302, 304, 303 and 2303. Had a comment from a toll collection person that it smelled like something was burning, although I can't seem to smell it. I have replaced gas cap and cleaned out air filter box/new filter while checking the visible vacuum hoses. No luck. Should I change out all of the ignition coils? Where is the MAF sensor located and should I replace/clean that? Any other ideas?
Thanks in advance for any thoughts, very frustrated at this point.

Any luck yet? I would suspect lower turbo hoses dot torn, loosened, or connectors for the coil wiring got wet. check all the vacuum lines from the bottom also.
