Do you mean the whole distributor assembly with shaft and all? What in the distributor assembly causes this to run rough? Is this a common problem for that particular engine? Your more detailed input would be greatly appreciated.

My '99 Quest threw a knock sensor code around 125,000 miles. Wound up replacing it and three injectors. I don't really trust that the indy mechanic knew what he was doing with the injectors. It's running and getting the same mpg as before but it's not as smooth as it was before. It was barely running after the CEL came on though; didn't matter if it was hot or cold. Missing, cutting out and you could smell the unburnt gas coming out of the exhaust.
The knock sensor is buried pretty good and just replacing that could run $500 to $700. Knock sensors run ~$175 and labor is 5.2 hours.
Please report back on how it goes.

Trust me, knock sensor is a symptom, not the problem. Go and get a rebuilt or used distributor from the wreckers, I stupidly spent thousands trying to fix this problem, this is a common problem with villagers and quests .... Distributor ...try it and repost.

There is a small photo sensor deep inside the distributor which gets fouled up with carbon and heat stress over time... find a good distrutor and clear the codes, you should be ok.....

About 5,000 miles before my CEL threw the knock sensor code, I had replaced my plugs, wiring and cap. fwiw...

I had just changed my stuff on general principles - didn't want the plugs to completely seize or a belt to break since everything was original at 125k. Never fails - been better off just to ignore the preventative maintenance.
And my indy mechanic wasn't too impressive either and I doubt that the dealer would have charged much more.

Nissan Quest Distributor Problem

Yes with the help of this board I found the problem with the 2000 Nissan Quest, The
distributor was the problem after getting warmed up and yet would run good when first started cold. I found the bearing in the distributors after the lubricant wears off from age and miles get hot and making the distributor get hot and this being the problem.
Some oil down the distributor shaft say ever 50,000 I feel will help, but this is a problem and a new distributor with this design will we not have the same problem at a later date once the bearing lubricant wears off?

I'm new here and was reading everything and it sounds I might be in the same boat as most of you...I have a 97 villager that is running rough and when stopped at a light you can hear the rumbleing 'brrrrrr" sound but when I put it in neutral as I wait for the light to change the rumbleing subsides and the engine runs smoother. Now I just got finished having to have it serviced to pass a smog test and 2 codes came up one of which was the knock sensor but they didn't replace it cause they said that it was not the reason for the CEL to come on, so they didn't...they just replaced what they called a EGRC-BPT valve and it passed the smog test. Could this knock sensor be the problem?....I am scared that it might be a tranny problem but then I saw all this talk about the distributor....any opinions???
