Hey guys - I drove my car last night and it seemed to run fine. I just finished reswapping it from another EK where the motor always ran well. This morning I went out to start it and the car turns over but doesn't catch and run normally. It has been really cold as well. I thought maybe a clogged fuel filter or clogged injectors? But then I noticed carbon build up in the throttle body after trying to start it a bunch. What would cause smoke to come out of the intake manifold? Is something clogged?
