Looking for any suggestions. I have a 91 YJ 2.5L that has began to 'sputter' at high rpms (2500 - 3000). It starts jerking until I let off a bit and then reapply gas slowly, but then when the RPMs climb back up it starts again. I bought it back in October 07 and immediately did a tune up (plugs, wires, etc) and then Nov replaced the fuel filter and water pump (which went out) and then in Dec the fuel pump went out and replaced it. Here it is the end of Jan and it seems like the problem started about 3 weeks after replacing the fuel pump. Of course as luck would have it, just last week the power steering pump went out so that was replaced along with a new serpentine belt. So here I am going into February with a sputtering Jeep (which happens to be my first) and wondering why the hell I bought it to begin with?? Oh, now I remember, someone told me I needed a hobby!! In any event, I really like this thing for some twisted reason and looking for advice on what would cause sputtering at high rpms. Everything is stock and it idles fine. Any suggestions?
