Another "help, hesitation" thread.

I've noticed lately the Jeeps starting a little more rough, sometimes it takes more time for it to start, and usually it seems to kind of...hesitate/sputter to a start. I've also noticed that when I give it throttle, there's a slight, maybe .5 second delay before it'll actually rev up. Any thoughts?

I have the same prob. What minimized the issue was changing the plugs as the factory were gapped incorrectly

I used ngk platinum. They are very easy to change. Just make sure they are gapped correctly from the store as mine were not.

Had similar problems. Replaced plugs, wires, various engine sensors (IAC, MAP, etc), cleaned throttle body, replaced air filter - all to no avail. Finally, I replaced the fuel pump and that has (so far) resolved the issue. Was relatively easy to do, as well.

Early on I was taught to Gap my own plugs. Never trust the Gap right out of the box. Just think how many times that plug has rattled around in the box before you open it. Never assume they are gapped per specs before install. Always check the gap and adjust if needed. If the gap is right that's one thing not causing the problem.
