Been browsing this forum for a good while now and haven’t seen any solutions for my problem. I have a 2000 TJ 4.0 with 90k miles. Over the last few months I’ve had an issue where first startup of the day or if it has been sitting for a few hours it will start up fine but shortly after will start to sputter and miss. If apply any throttle it will bog and try and die and backfire in the airbox. After a few minutes it will jump up to 3k rpm and will idle perfectly fine.
No codes
new plugs, coil pack, and B2S1 o2. Cal emissions. Throttle has been cleaned. Any idea what the issue could be?
PS MPG is between 10-13 hwy not sure if it is related rolling 33s
