Idles Rough

I recall the old napZ engine did that quite a bit and would end up burning a valve if the owner ignored it long enough. Seen any of the altimas do that?

Well, I guess it could be worse, but it does seem like it's a leaky manifold gasket around number 4. When I spray carb cleaner around this part of the intake manifold, the idle does smooth out, a very small amount, but it is noticeable. It's darn hard to get at this area, so perhaps the leak is on the side of the intake port that I can't reach and the fluid is being sucked around to there. While sitting in the driver's seat, the part of the port I can apply carb cleaner to is at 10 o'clock.

I've got the Haynes manual for the car, but this job looks like a knuckle-bleeder. I've got no idea how much it would cost to have it done, so at this point I'm not sure what I'm going to do.

Luckily, my registration was due mid-May, which I've gotten, but a smog check was not due this time around.

What to do, what to do...

Thanks so much to all that responded in this thread. I'll be back.

Sincerely, Bruce

Then you've found the problem...
