00 Max, rough start issues
Okay so I have been plagued with this issue for over a yr now. I have replaced so many different things on this car. It runs fantastic once the car is running, but the at starting point the car really has trouble, choking and not turning over.
These are the parts in the last yr that have been changed.
Starter
Camshaft sensors "left and right"
Battery
Spark Plugs
Fuel Filter
I have tested the Ignition coils and all are working 100%, I have no codes what so ever for the length of this issue. I have also cleaned and tested the MAF sensor as well and to no luck. But cleaning it however did gain a lot of power back. I have no stall, or lost performance during driving. It gets over 3500RPM, so I don't think the MAF could be the issue. I did however notice after changing to a K/N filter about 2yrs ago this issue has arised, however the MAF has never thrown a code and it tested "working". I have worked on this car myself for mostly everything, but have had many Nissan dealers look at it and smaller mechanics and to no luck have they been able to diagnose the issue. I also have had the timing chain checked, and the tensioner and that was all good as well. It's a 00 Max with 132k miles, and like I said once its running the thing is flawless.

The problem is your upper intake manifold gasket. It is sucking air until the engine warms up which expands the old hardened seals. I have replaced several of these to cure cold start issues.

So what about the lower gasket? I just got the upper one and am about to put that in now. Would the lower one have issues as well?

Don't think it could be that only because no code is being thrown what so ever. I do however now think the Upper gasket is the issue, only because I used Seafoam back at 100k miles and that probably wasn't a swell idea with an old gasket. So i'm sure that ruined the gasket by using it.
