Help!! YJ stumbles and misses

My 1995 YJ 2.5 will run fine and then start missing and running rough like water in the gas or starving for fuel. Then at the same time will seem to have a burst of power. Any body have a similar problem and found the cause. I know it could be a multitude of sensors,Any info would be greatly appreciated. I,m leaning toward throttle position sensor or temp sensor.

BTT for ya

When did you fill up the gas tank? Might try a bottle of dry gas and see if that helps... only cost a buck or two.

Hope you figure it out.

stumbles and misses

I had done the dry gas and injector cleaner as I suppected water in the fuel. Still had the problem, Found today the connection to the PCV valve was not secure. Took care of hose decay and a hose clamp and all is well.Running strong and smooth now.

You got a pic of what you had to check/tighten? My neighbor's YJ is doing the same thing and I'm trying to find a list of things for him to check.
