Replying to: gatchison (Feb 28, 2009 8:26 am) However, in the past few weeks (and at 68k miles), the car will NOT stay running unless I gun the engine immediately after starting it. It happens every time I start my car. It does not matter if the engine is cold or warmed up. I am taking it in this week b/c, in addition to the stalling issue, the driver's seat no longer adjusts on the right track. Randomly one day last week, the seat moved back when I turned off the car and then when I started it up (and gunned it!), a very weird noise came from the beneath the seat. Fortunately, I can reach the peddles enough, but it is inconvenient. No one shorter than I am can drive my car. The seat will move forward on the left track, so the seat just moves diagonally toward the gear shift, while staying fixed on the right track. And nothing is in the right track. I believe the motor burned out on the right side. Ugh!!! I will keep you posted. Of course, the warranty is over. This was my first Nissan. I had always been a Honda girl, where it was normal to run them to 200k without issues (wear&tear excluded). Is this normal for Nissan?

Replying to: gohokiees (Apr 20, 2009 8:52 am) Several months ago,, the driver's seat just stopped moving back when you turn the car off.At least I can still position the seat, it just doesn't move like it did when i first got the car. Please let me know if your dealership has found a reason for the starting/stalling problem. I can deal with the seat for now . . . .

Replying to: gatchison (Feb 27, 2009 9:48 pm) Problem started after replacement of the battery????? Wonder what the cause and effect is. Took it to the mountains, and never failed to idle when starting, hot or cold. Wondered if it was the altitude??? Came back to Ok, and now the problem is there again. Obviously the 'clean out' from a long trip was NOT the answer. Maybe the low octane gas I use causes the knock sensor to shut it down??? Will try a tank of premium next time gas prices come down. |

Replying to: c8smom (Aug 05, 2009 10:30 am) I removed the THROTTLE BODY and cleaned it with a can of carb-cleaner. There was a lot of build up, but I did not think this was the root of the problem. I reinstalled the THROTTLE BODY and started the vehicle. This fixed the stalling issue, but not the rough idle. I removed the THROTTLE BODY again for a closer inspection of the area. What I noticed was a small area on the opening to the intake that was dirty. The metal crush gasket that is between the TB and Intake somehow developed a leak. I could tell because everywhere on the intake where it mates to the throttle was clean except for this small area on the radius. (the stall was probably fixed the first time because I might have caught the gasket just right and stopped most of the leak) I cut a new gasket out of good gasket material. Reinstalled the TB, reset the ECU of soft codes and started the vehicle. No problem. Idled smooth like when we bought it. In conclusion: OUR particular problem stemmed from a leak between the throttle body and intake. Hope this helps.

Replying to: ferraritech (Aug 23, 2009 6:57 pm) Note: Carb Cleaner is highly flammable. Use extreme caution and try to do this with a cool engine. (you can substitute carb cleaner with WD40- result isn't as noticeable) Get the engine to start and run on its own (if you have to have someone hold the throttle that is fine) Quick sprays of carb cleaner directly at the area between the throttle body and intake. Get the top, sides, and bottom if you can. If you have a leak there, the engine will stumble and possibly stall. Next step...go get another gasket. As far as I know, there are no aftermarket fiber gaskets for the Murano. So you will most likely have to go with Nissan's metal crush gasket. I would say this is probably fine, but if it happened once......
