Default 97 ZJ start problem 4.0

I have a 97 ZJ with the 4.0 in it... Good jeep... Love it! But every now and then it don't want to start and when it does it wants to stall out if I don't keep my foot on the gas... But everyother time it starts first try.... What could be my problem? I just changed the wires cap and rotor button

It could be that your fuel pump is not giving enough pressure or your air filter clog.

My 98 zj did that to then it got to where it wouldn't start at all. Come to find out it was the hot wire for the starter had came off the terminal at the battery. Maybe check your connections
