Question about 2005 Audi A4
About two days ago, my 2005 Audi A4 1.8T QT started to misfire. The car would shake and hesitate, mostly noticeable at idle but also during driving. Check engine came on and got it checked at autozone and came back as P0304, cylinder 4 misfire (vacuum leak on engine). I changed all four spark plugs and the problem is still there. And the coil packs are only a year old. I also put into fuel injector cleaner, it may be a vacuum leak but I looked and didn't see anything, but maybe I'm not looking at the right hoses?
I too have the same problem on my 2005 1.8t B6. I noticed a hole in the breather hose coming off the valve cover that runs to another port under the intake manifold. I have the hoses on order and should be here on Wednesday. I'll post again if that fixes my problem.
