So I have a lq4 turbo swapped car. Car was running great at the end of last year until it developed a bearing knock. Over the winter I pulled the motor and I just got around to putting it back together and tossing it back in the car. Well the car idles great with good air/fuel. But once I take it up the road it’ll start to spit and sputter like it’s running out of fuel. It’ll go lean and sound like it’s underwater. If I let it run for a little bit it’ll clear up and idle great and not have a miss. It’s got an aem 380 pump. I checked the fuel filter, it’s fine. I pulled plugs. Bank 1(cylinders 1,3,5,7) have almost oily or gas fouled plugs.
Bank 2 (2,4,6,8) plugs all look good. Can anyone help me figure out what’s going on? The car sat all winter with battery shut off. Car isn’t using o2 sensors
