    1. When does it misfire and what can you feel, hear, etc?

    2. Brand of plugs, coils and maf?

    3. Have you done the block egr flow test?

    Starts with no cost egr block flow test


    At about 10:15 in the video he starts talking about the egr valve letting "air" into the intake manifold. He means exhaust gasses. A blocked egr cooler won't cause death rattle or misfire codes. A sticking open egr valve can cause rough low speed engine operation. Both will cause an egr code. Neither will cause loss of coolant.
