need help sputtering problem
my a4 1.8t has a bad sputtering problem. it runs really rough and sometimes won't even accelerate. ive already changed the mass air flow sensor and the throttle body. it threw a code that said (left bank 1 too lean). i think that was from the vacuum leak. ive already fixed the vacuum leak and its still running like crap. someone please help!

yea the check engine light is on but i havent turned it off after i fixed the vacuum leak. it idles really rough and when i try to accelerate it will start sputting and wont accelerate.most the time when i gas it and it hits about 4,000 rpm it starts shaking and the rpm doesnt move. kinda like a misfire

yea ill get that looked at in the morning and ill get back at u. i guess if theres no more codes ill buy a coil pack. and swith it out one at a time to c if that fixes it. let me know if u got any more suggestions though.I appreciate it

yo i had it checked out this morning and it came back with a new code. (knock sensor) i know the motor isit knocking. i think its from it running so rough. but i cleared the codes ive been driving it all day and the cel hasnt came back on. u still think it could be the coil.
