im not really a mechanic, but my guess is a fuel delivery problem. it will be on the side of the engine with cylinder 1, (bank 1). probably an injector.... -
Could be injectors or maybe you need a tune up just my guessComment

O2 sensor....bad coil pack....Comment

engine performance.
Unmetered air can enter the engine through a vacuum leak, a dirty airflow sensor that is not reading airflow accurately, an EGR valve is not closing and is leaking exhaust into the intake manifold, an EGR valve that is allowing too much flow (because the EGR differential pressure sensor that monitors EGR flow is faulty and is under-reporting EGR flow).
It can also be caused by low fuel.pressure or dirty injectors all this info is online if that helps you.Comment

X3, start with the coil pack, pull the plugs and look for fouling to determine cylinderOriginally posted by bwssr View PostComment

It is acting more like fuel delivery than a misfire. But I will be checking all the suggestions. Thanks.Originally posted by PSD Ryan View PostComment

Something on bank 1 makes it run rich, so it could be a leaking injector, leaking fuel pressure regulator, a bad spark plug, coil pack, a bad o2 sensor before cat on bank one.
Time to check the basics then go from there.Comment
