I drive a 1991 B2200 Mazda. Five speed, 114,091 miles. For the past 4 months I have felt what I thought was me unconciously easing off the gas and the truck very slightly chugging because of it. Two mornings ago, I went to step on the gas and it wanted to die, I swore at it, lol, being truthful and stepped on the gas even more and it was fine after that.
What is causing this problem?
Bad gas? I have not added any water in gas treatment.
thank you

There can be a few reasons that may cause your problem, firstly any diagnosis should start with a scan for any unresolved fault codes, a general tune including the fuel filter and if the filter shows any signs of water or contamination this should be looked into, my first thoughts are a defective TPI (throttle position sensor) a scan will extract a code for this if it is faulty.
