All of a sudden, my VQ35DE began to act up on a cold start. Before that, it would start in a fraction of a second after several cranks by the starter. Now it takes over a second to start in the morning. For about 1-2 seconds immediately after the start, the engine does not run smoothly. It does not sound like it misfires but rather it is missing the ignition cycle in a cylinder.

It only happens in the morning during the cold start. It is usually about 90 degrees outside when it happens.

Should I bring it into the shop? I'm hesitant about that. If they cannot reproduce the problem easily, they may not want to look at it. None of the "bad" lights on the dash lit up. Engine is stock and it has always been this way.

What would you recommend?

 

well... i dont know much about engines and their problems.. but i do hve an idea for you so that the dealer can reproduce the issue. have your car towed to infiniti. its going to cost you, but at least itll be cold when it gets there

 

It looks like the battery died. I'll be taking it to the dealer for checkups on the electrical part.

 

the dealer will just keep it overnight for a cold start no big deal

 

yea. take it to the dealer.
