My 2000 expy 5.4 with 128k miles started yesterday but ran really rough. Drove it around the block with a very noticeable loss of power and missing fire. How can I access any trouble codes there might be to help me understand what happened and what needs fixing? Will accessing the trouble codes identify which cylinder is missing fire?
