Question about 2002 Nissan Xterra

1 Answer

2002 Nissan Xterra Supercharged

I was wondering if you knew what was the problem or what could cause my 02 Xterra from running rough like when you would sometimes sit at a light waiting for it to change? I bought it with 40,000 miles on it and run high premium gas as it recommends. I tried cleaning out the injectors with a $15 bottle of additive for the fuel that was recommended. It also takes a while to start. I was thinking the plugs next or the pcv valve. What do you guys think? The air filter is also clean and it has about 70,000 miles on it now

thanks for your time and consideration in this matter.

Chaz.

Changing the plugs is a good idea. The pcv, pop it out and give it a shake, if it 'rattles' put it back in. Now with starting fluid, check for a vaccum leak around the intake. Do this with the engine at idle speed, it will pick up when you hit the spot. Install the gasket or replace the hose that fell off, Way ya go! Frankster016

Would a bad fuel filter cause the engine light to come on and also make my car run rough


A bad fuel filter can make the engine run rough, but by itself it won't make the check engine light to come on. It may have caused other symptoms and that's what is making the light come on.

No check engine light on runs rough while in gear


Plug Mis-firing (firing-but not adequately) no light and no fire.
Causes: Spark plug bad, spark plug wire leaking.
If you can pull the spark plugs - and you find that one of them is wet or very dirty - compared to the others....the you have the wire/plug source identified.

02 4Runner 3.0 showing service code 300. Replaced


Replace all your plugs, po300 code is random misfire which could absolutely be caused by bad gas causing detonation. Try an octane booster and gas stabilizer when parked for long periods.

Hi I have a 2001 Xterra, Manual, 213,000, runs rough at random


If your mechanic changed the spark plugs. Make sure he did a few things.

First make sure he used NGK plugs. I have seen other make plugs cause running conditions.

The other thing is make sure plug number 6 was changed. I can not tell you how many times I have seen shops leave that one cause it's to hard. That also can give you the ruff condition.

Last but not least, if the distributor cap and rotor and wires were not replaced, it may be possible that you could have a spark issue being loss. If you notice it more when conditions are wet, then it has to be related to those items.

Thanks Jay!

02 VW Golf runs rough after sitting in the rain.


Water is probably leaking onto your engine somehow and shorting out the plugs.
