Why does my GMC Savana 2500 misfire so much?

Asked by Apr 06, 2014 at 11:06 AM about the 2002 GMC Savana 2500 Passenger Van

Question type: Maintenance & Repair

When I used a scanner to troubleshoot, it shows the same error twice on the same
screen. Mass Air flow sensor and Evaporative Purge Solenoid valve. I have replaced
both already, reset computer and the service engine is still coming on. I have changed
the distributor, cap, rotor, spark plugs and wires also. When scanning the codes, the
same codes are shown. The van still misfires under load and mileage is horrendous.
Am i looking in the wrong places? Can someone please help?
