HELP 2.5 bogging down

[Steven Seimer]

I have a 1997 tj with a 2.5. I recently did a tune up because it was bogging down and almost have to put your foot to the floor to get it to move. needless to say it did not help. I have checked every vacume line and every plug on the wiring harness and still cant figure it out.:???:

SOOOO ANY HELP WOULD BE GREATLY APPRECIATED!!!!

How does the flame on your plugs look. If not nice, and blue, it is on your ignition system.

Is it throwing any codes? I have the 2.4 ('03 TJ) and when my O2 sensors went bad, I had no power and my gas mileage cut in half. Just a thought.

Does it bog down after running a while, or from the start?

 

[Steven Seimer]

Bogs from the start have not had a chance to check codes installed a acell super coil today still nothing. Ran some seafoam through the vac system and added some to the fuel today also. Will check for codes tomorrow.

Well it is throwing codes for the O2 sensors. Just dont know what one so I will be replacing then all. Hopefully this works....
