yes.
Infiniti Mechanic: Jay, Certified Infiniti Technician replied 2 years ago
Is that fully warmed up? Those are both high readings at idle.

Customer reply replied 2 years ago
Jumped to 27 both of them
Infiniti Mechanic: Jay, Certified Infiniti Technician replied 2 years ago
That is odd, the timing is even high for 7.1 or 7.2.... How many miles on the car?

It's going to be tough. I have to return it back at 5pm. What do I need to test? I'm guessing getting reading under load, idle, start up? Let me know what else I need to check.

Could a flywheel be a cause and how would it cause it?

Well I want to be able to spend time helping you but I am currently working. That is why I ask if we can continue later this evening.
Is that possible?
Ask Your Own Infiniti Question
Customer reply replied 2 years ago
It could be possible but what should I get readings for? I have to return it and I can't get it back
Infiniti Mechanic: Jay, Certified Infiniti Technician replied 2 years ago
Sorry, I didn't realize this was a rental scanner and it had to go back and that is what you meant by time.
Did this car have any type of major engine work before this happened?

Needed to check intake timing
Customer reply replied 2 years ago
I changed the rear timing gaskets due to p0021
Infiniti Mechanic: Jay, Certified Infiniti Technician replied 2 years ago
Thank you. Since you have been in the timing area, either the timing is off 1 tooth on each side, or your intake timing sprockets are bad.
When you did the timing chain work, did you disable the fuel system and turn the engine over to build oil pressure up first?
If you didn't, it could have jumped a tooth or two.
You are going to need to remove the front timing cover again, and check your timing. If your timing is good, then you need intake sprockets. If the timing is off, then I would set the timing and re-assemble. Unless you want to replace the sprockets anyway so you know it can't be anything else in there. That is up to you.
If you have any more questions on this, please feel free to ask.
If not, and you're satisfied with my help, please Rate me. I hope I have provided you with Excellent Service.
Thanks Jay!

Would a vacuum leak contribute to the problem. Or the flywheel. Idk if it's damaged or not for the hard shifting.
Infiniti Mechanic: Jay, Certified Infiniti Technician replied 2 years ago
Vacuum leak really won't affect the timing.
I can't see the flywheel being a problem, unless it was removed and installed for some reason.
There is a TCM update for Harsh Shifting.

I have a autel maxisys. Would that be able update the tcm
Infiniti Mechanic: Jay, Certified Infiniti Technician replied 2 years ago
I am not familiar with that scanner to be able to tell you. It would have to have the software on it for the Harsh Shift update. Which I know is on the Dealer scanner. I have done a ton of them.
It's highly unlikely that the scanner would have the software to for the harsh shift.

Customer reply replied 2 years ago
this may be random but, could this part 15200-EY00A or 15200-AR000(idk which one it is) cause the problem. i remember noticing that it was missing on one side. heres a pic 15200N

Hello
Infiniti Mechanic: Jay, Certified Infiniti Technician replied 2 years ago
Yes, Those are the Screens. You need to have those to filter the oil so nothing jams up the sprockets.
Ask Your Own Infiniti Question
Customer reply replied 2 years ago
how come the hard shifting happens when the p0345 code comes on. would it make sense to update the software. how would they be related.
Infiniti Mechanic: Jay, Certified Infiniti Technician replied 2 years ago
Cause the cam sensor also causes a engine speed signal code. Since it looses engine position signal. When it finally sees it, that is when you get that hard shift.
