Most likely a fuel leak or sticking injector. Try injector cleaner first to see if it helps. It probably won't but it's worth a try.
Lifespan depends on the owner and how well you take care of it. regular oil changes and maintanence will help. Mine has 250000 miles and it still runs strong..
It is 36mm. A 1-7/16 inch will also work. The sockets for this are readily available at auto parts stores. Have you got a good strong breaker bar, because those babies are on there TIGHT!
Just a guess, but it might be a leaking fuel line, meaning the injectors aren't getting enough fuel into the cylinders, and that's also where the smell is coming from.The other thing you could check is your spark plugs. It sounds strange, i know, but I've seen that happen. If your spark plug isn't sparking, you'll smell gas, because it isn't getting burned. Also would explain your rough starting.
use a flat head screwdriver, put it underneath the bottom layer of the vent, and slowly shimy the screwdriver up and down until the vent pops out. be careful not to be too careless and strong doing this, for your vents will be in pieces in your lap.
Car will not start, makes no sound. Battery is strong.
I have a '98 Nissan Pathfinder that has over 371000 miles on it and still running strong.
it causes strong winds
Strong winds
the wind!
I have 302,000 on it and it is still going strong. I change oil every 3K
Could be a number of things. Check the fuse first. If that's OK, make sure your battery is strong enough to power the seat motors. If that's OK. check for disconnected or broken wiring under the seat. Finally it could be a burned out or defective electric motor, or a relay.
Lots of vinegar.
