I just bought my truck about 6 months ago, immediately I had to get my plugs and wires changed, my truck was progressively getting worse and jerking really badly when accelerating. My plugs we messed up again with I two weeks, they finally figured out that the thermostat was stuck open causin the spark plugs to go bad almost immediately. After fixing that it ran like a champ for about 5 months and now is beginning to do the same thing. It starts sting, but very rough. It takes about 10 seconds to even out and run smoothly. Any suggestions to what could be causing this? I know of a couple people who have to change out plugs on their rangers every few months.
