The only thing left is the fuel injector or a leaky/sticky valve. Scan for codes if it might be electrical.
Only code is p300, p301, p303, p305. I've checked fuel trim etc. Even flashed pcm
Replaced the cylinder heads, timing belts, and tune on my 2010 terrian 3.0. Now bank 1 (right cylinder) is misfiring when idling down. Any ideas?

My 2010 Terrain feels like it’s dragging passenger rear tire when making sharp left turns, u-turns to left, makes noise and difficult to make the turn like it won’t turn sharply.
