Re: **power loss uphill**
O2 sensor changed in that tune up?
Re: **power loss uphill**
no..i bought the jeep with 65k and now has around 70k and i never replaced the o2 sensor cause it seems to run and idle fine...not sure if previous owner ever did..
Re: **power loss uphill**
They are the most neglected tune up part there is. My opinion is that they be replaced every 50K, which is generous considering Jeeps says 28K. A lean or rich mixture due to faulty readings on it will rob the engine of power
Re: **power loss uphill**
hmm. makes sense to me.. i will replace it this weekend and update..
thanks 4.3LXJ!
Re: **Power loss uphill**
UPDATE: replaced o2 sensor and power is way better now... driving uphill is a breeze and no more sluggishness.. didnt think o2 was faulty but after replacing it engine runs alot stronger.. thanks for the help!!
