I did a full coolant pipe repair on my 03' 745i. Got the pipe from eBay. So far no problems leaking wise. Now I also changed the gaskets as well. I have a misfire and also something about injector 4? Here's a list of codes. Which prior to me DIY was just fine and clear.
Po204 injector open circuit cylinder 4
Po363 misfire detected fueling disabled
Po430 catalyst system efficiency below threshold bank 2
Po116 engine coolant temp system 1 circuit range
P1357 manufacturer control?

Any help guys??? I'm pretty good with tools and don't want to go to dealer
