95 isuzu Rodeo Engine Sputters

[llizards]

My rodeo had the furl filter changed then the engine light came on. after 4 tanks of fuel injector cleaner the light is now off but the engine sputters bad... acts like its passing water or a cylender is missing out.. All spark plugs are new and are firing... any ideas? I have 112,000 miles

Check all your vaccuum hoses. I just replaced all of mine because some were splitting. What a difference, more responsive engine, and better milage. Not sure if it'll help but it is cheap and easy, and a good thing to do on a 10 year old.

While I was at it, I gave the EGR pipe the "treatment"

but did you check the egr valve itself to dee if it was stuck open if its open all the time it will run rough at idle and low speeds

Change the wires and now she is running like new... all vac lines are new about 2 months ago, EGR valve working fine... turns out to be just the wires...
