My 2005 Nissan Altima has an odd habit. I don’t know how long it has been going on, I bought it in Oct and noticed the behavior shortly after. Here are some symptons.
While driving the check engine light will flash anywhere from 30 seconds to normally not more than 10 minutes.
When I am driving with the flashing light there is a jerky motion, like a misfiring engine, but only under 2100 rpm.
Above 2100 it is ok-ish
When I am stopped in P or N during that time the car vibrates more than normal.
When I am stopped in D during that time the car feels like it is about to stall. (It never does)
If I am in R it is ok-ish.
Once I park the car and let it sit during the work day, or over night the problem may or may not return. When it goes away, it can go away for weeks at a time.
I feel like it mostly happens when the tank has 1/4 or less of gas or was just refilled. But, I haven’t paid as much attention to that detail.
The mechanic can’t get a code read and can’t reproduce the problem.
One day only, I managed to get a code that cylinder 1 is mis-firing.
He has another Altima with the same problem he has been diagnosing for a while and can’t find a solution.
But, I find when I come here I always get good feedback, so, if anyone can help on this, I would appreciate it greatly.
