Welcome to FTE frappis.
It would seem the computer thinks is unhappy with the air fuel mixture in bank 2 & this would suggest a number of possibilities, maybe something is wrong with a fuel injector, or maybe fuel pressure, or even an air leak thats affecting just bank 2, or perhaps the O2 sensor for that bank is acting out.
So a little more info might help in deciding which would be the next thing to look at.
Which engine do you have in your 98 Ranger & how many miles on it????
Do you have any driveability problems???
Do you hear any ping from a lean mixture????
Did this problem come about suddenly after some event????

Sorry for lack of info...the truck is a 4.0 auto 4x4 with 125k & jet chip...I changed the o2 sensor(bank 1 &2) about 10k ago. also I just cleaned the filter on the cold air intake(the filter was pretty dirty) it does start to sputter while going down any sort of decline---once the road levels out she runs fine?? tom. I will try the MAF---thankx a bunch for the tips!!!!!!!
