Engine woes

I did some searching for this, but I'm not sure how to phrase it, so I didn't come up with much.
I need some suggestions for some 4.0 engine fixins. It's for my 97 manual TJ Sport. Nothing's really broken, but the poor thing is struggling. So far I've replaced the battery, sparkplugs, rotor, cap, and wires.
Any help?

Hesco Stroker kit. If you're running rough after doing a pretty decent tune-up, your rings may be bad and may need to be changed. May as well replace it with some good stuff while it's all open. Then again, you can change rings with the engine still in the bay, you can't change the crank unless you take it out. A set of sockets, a breaker bar, torque wrench, piston ring tool and rubber mallet should be all you need to do that.

Try changing your fuel filter, and cleaning/replacing your fuel injectors to finish the tune-up.

Hmmm. I just read up on Hesco's kit, and I like the sound of it. How much is it and where can I get it. Do you think it would be worth it to put a stroker kit in an engine with 127,000 miles on it? Or should I just let this motor run it's course, and then replace it with a stroked engine?

How is it struggling? Accelerating? Normal driving?

Before you blame the engine (127k isn't that much), then check the simple things. For example, the cat could be stopped up. This would drain your power considerably. Check the simple things before you invest in potentially un-needed expensive fixes .

Stroker kits are never unneeded. But yeah I agree, the cat could be clogged.

And stroking that engine will essentially breathe new life into it, seeing as how it's only at the midpoint of its life to begin with. You may also look into a cam and a new valvetrain if you feel so inclined. This is all for upgraded performance rather than fixing an existing problem, so do things as you see fit, of course.

There's no real specific problem, it's just not its perky self lately. I do have a new high flow cat sitting in the garage, I'll see how it does once I get that on. I am pretty sure I have some sort of fuel issue. Whether its the pump, or the injectors, or something else, I'm not sure. Maybe we can steer this thread in that direction...
