MAZDA B4000 ENGINE PROBLEM

1998 Mazda b4000

Engine Performance problem
1998 Mazda b4000 6 cyl Four Wheel Drive Automatic 168000 miles

My 1998 Mazda B4000 runs great around town but anytime that I drive over 30 to 45 miles without stopping the truck begins to misfire and run rough. Any idea would be much appreciated. Was leaning towards a possible mass air flow sensor.

Hi there,

Start with a scan to see if there are any unresolved fault codes, you don't always get a check light with all codes.
