I have a 1999 b2600 that keeps coughing and splattering. I have replaced the spark plugs, leads, dizzy cap, O2 sensor & put a second hand air flow meter on it. I have also ran a diagnostic test on it the only things that came up was the o2 sensor and the air flow meter (this was before I changed the o2 sensor). I reset the codes and ran perfect for about an hour and started to lag again. What could be causing it to splatter? Any help will help thank you.
