I HAVE A 2003 NISSAN,PATH FINDER. TOOK IT TO THE SHOP TO REPLCE THE SPRK PLUGS AND WAS TOLD BY THE MECHANIC WHEN I PICKED IT UP, THAT HE REPLACED ONLY FOUR OF THEM. THE TOW IN THE FRONT ARE SEIZED AND VERY DIFFICULT TO REMOME. WHAT DO YOU RECOMMEND TO DO ? . MANY THANKS..ABE

get a new mechanic who knows what he is doing
plugs for ECM controlled engines very seldom need changing ( most will last for 5 years or platinum plugs will last a life time )
--- nissan , toyota , mitsubishi and other cars with v 6 engines where it is almost impossible to replace the rear plugs all use platinum plugs for those plugs as they are never replaced --
if you need 6 coil packs then the engine would not be running
best find an accredited service shop with experience on your vehicle , have the codes read and have the problem fixed properly
with fault code storage in the ECM, repair by replacement is not an option but a total waste of money

Google rough idle problem 1995 Nissan, and check just how many solutions there could be to that problem...but most likely is idle air control valve IAC.....

gap on spark plugs was OK,cap and rotor is good [quality]air filter,fuel filter,dirty throttle body.

air filter, fuel filter , bad fuel find dependable reputable mechanic

The back three spark plugs on the V6 are difficult to reach without a socket extension. if part of the engine is hindering you from taking out back plugs. then remove the part thats in the way. then replce when done. have a good day !!

If everything is running fine, I would think you could wait. It is rather involed to replace them. With all that is involved with replacing the back plugs, if I was the mechanic, I would have highly suggested replacing them at that time.

Yes it could be true if the mechanic needed an helping hand and felt he should call on another mechanic specialised in a different area from his to handle it.

1. Fuel pump issues are handled basically by an auto-electrician.

2. Tank related issues are handled by a mechanic or panel beater.

Consider he had told you the truth.

Cheers and rate this.

Only if your vehicle is affected byt he recall. When a manufacturer issues a recall they have to specify a specic date range and model range. for example 2000-2003 Nissan sentra XE's with build code ......

yep po132 shorted to voltage po152 shorted to voltage.this means lean conditions .you got in take leak .if you get a high voltage conditions you got rich mixture.bad plugs or stop up air filter.

I had a 93 Nissan that had a similar intermittent problem running when wet, humid or after sitting. Usually it would start fine and run well most of the time, but stutter, shake or die. It sometimes had low power and got terrible highway mileage even though it was a 4 cyl. 5 spd. When it was dry and not humid, it ran like it was new. I thought it was the ignition wires and changed them with no results. 2 Nissan dealers said everything was fine--it never acted up when they had it. I found a web site that had Nissan technical service bulletins and found one that described the problem--there's a connector in the wiring that needs replacing. It's wrapped in black tape and is a crimp connection. Dealers told me that couldn't be the problem (it was still under warranty), so I took the truck and bulletin to a non-Nissan mechanic. Within an hour he found the connection, replaced it, and the truck ran perfect after that. Sorry but I don't have the technical service bulletin anymore. I may have found it under a different year . .Good luck.
