Question about 2002 Nissan Quest
We just purchased a 2002 Quest with 89K miles. Our 5th nissan in the family. In comparison to our up-for-sale 2000 Buick Century with 136K mi, Nissan's engine is little rougher, louder, and kind of jerky. Buick's is smooth as a butter. What should I do to make this go away? Start with spark plugs? I don't know if the dealer has serviced it except oil change and detailing before the sale. I mean the van runs fine, but not silky smooth as the Buick. I can tell the difference. Maybe we are just not used to the new v6? I would also like to replace a fuel filter and hear your recommendations on any other stuff to do. Is there a timing belt or just chain?
So, should I change:
1. spark plugs
2. distributor cap (needed?)
3. fuel filter (should be easy)
4. timing belt (if no chain) - but this would have to be taken in, too complicated
Go here for all the help you need
clean your MAF sensor first. Use spray carb cleaner and toothbrush gently. 2 wires in there get coated with varnish and lean out fuel mixture.
MAF in air intake.

I own a 2002 Nissan Quest SE with 160,000 miles. Bought it with 119,000 miles. I had experienced the same thing short time after I bought it. Was running a little rough at one time, went through a rough patch with it, but now it runs great.
In 5 years of ownership, this is what I learned, through trial and error and spending quite a few $$$ being ripped off by unscrupulous mechanics.
For a tune-up which I do myself---really not hard to do, use either NGK or Bosch "double platinum" spark plugs. Double platinum is the oem recommended plug for 2002 Nissan Quest. Use good spark plug wires like Bosch. Get a Beck Arnley distributor cap and rotor from Amazon--- good price to be found there. Change the fuel filter and air filter: Fram or STP filters are fine.
Use 5W-30 oil for oil changes, for all seasons. Van runs great all year round with 5W-30. Change oil filter at every oil change too. Use good gas from BP or Shell; I use the plus gas, not regular.
Check and monitor all fluids regularly; engine oil, transmission fluid, brake fluid, power steering fluid and coolant.
Clean the throttle body with throttle body/air intake cleaner; clean the Mass Air Flow sensor with MAF Sensor Cleaner only!
Clean the IAC Valve (Idle Air Control) with throttle body cleaner or MAF sensor cleaner. Either cleaner will suffice.
There are good how-to videos on you-tube.
For your brakes, use Wagner Quickstop semi-metallic brake pads. Semi-metallic are oe pads.
(I tried Ceramic and Wagner Thermo-Quiet brake pads: neither were good).
I've done all of the above myself with help from you-tube videos, asking people who know about cars and reading online material readily available. You have to sift through the junk to extract the good material, since some people give horrible advice on how to repair or replace things on vehicles.
My timing belt broke 85 miles from home and it was a costly fix; between the towing and the mechanic replacing the belt and water pump. I neglected to check the timing belt; If I would have been more mindful, I would have saved $340.00 on towing. The timing belt and water pump replacement ran over $450.00. Lucky for me, the engine is a non-interference engine so no damage done to engine when the timing belt broke.
If the timing belt has not been changed or you are not sure, it is imperative that you have it checked and replaced (if necessary) since you are reaching the 100,000 mile mark, along with the water pump. Make sure to do both. It is a costly job and they should both be replaced at the same time. Don't let a mechanic tell you different!!!
Check your drive belts for wear and tear. There are three belts, not too expensive to be changed. But just as important also.
Sometimes or even most of the time, unscrupulous mechanics put in cheap parts in your vehicle and you end having to go back to them sooner than you should. I always do research on what the problem is with the vehicle and what I would need to get it fixed and buy it myself, do it myself, all to save money. If not, I bring the parts to the mechanic and stay there watching till the job is done. I've saved thousands of $$$ doing many things myself. With the money I saved, I bought tools to fix my van.
