codes 1107, 1404, and egg smell at high acceleration. replaced EGR valve, and both O2 sensors still has check engine light on. Engine also idles with a little hesitation. Slight ticking sound from motor when at idle. oil changes always before time. found dirty air cleaner, didn't fix problem. replacing and paying is getting costly. any hints?
