So, I think its just time for new spark plugs, but wanted to check other people's opinions. I have read some similar threads on the forum, but most people seem to have more severe symptoms than I have experienced:
2006 TJ Rubicon
has around 90,000kms(56,250 miles) on it, purchased new in 2006 with 0 on it.
I have noticed in the last few months that the acceleration seems to hesitate sometimes, in the lower RPM range. Also, in general it doesn't feel like its as responsive as it used to be.
It never happens at constant speed, only acceleration, and only lower rpms. There are no sounds or any other symptoms (though it does seem to have slightly worse mileage).
any comments are appreciated.
