Idle problem was caused by the opti .. I replaced with a oem opti and problem was fixed. But now i hear a ticking sound on the passengers side head. Its kinda loud it sounds like if it was low on oil.. But it isnt..

Ne one have ne ideas?

Thanks

 

Check your exhaust manifold bolts tightness

Mine were loose and made a ticking noise that got louder while acclerating

 

I had a broken bolt in the exhaust manifold and could hear a ticking. When i replaced them i still heard a noise which turned out to be the air pump check valve on the manifold. Now it is quiet except for the aftermarket headers between the Y pipe and the headers. Well work on that soon.
