Gas Pedal Delay

"The car does generally lack torque in the low revs. It's a V6." Whatever.
My 2012 FJ Cruiser is a V6 too and it does not bog when the weather heats up. Its not a drivers issue, poor maintenance, poor tuning, etc. Its a FLAW. Sorry that we are raining on your "Nissan can't be wrong" parade. I'm done reading YOUR posts on this, and will continue to see if someone else posts something useful to help solve this NISSAN FLAW on this thread.

Yeah, I'm the Nissan Can't Be Wrong guy I'm also terrified of the fact that you'll never read any of my posts on some message board. How do you expect someone to help you with this NISSAN FLAW? Have you investigated all possible causes? Can you repeat the problem accurately under a given set of conditions? Have you tried modifying those conditions in various unbiased ways to see which of the conditions might be unrelated? Can you accurately describe this repeatable problem in excruciating detail? Does that exactly match up with the symptoms of everyone else you're ganging up with on this issue?

Make an effort to rationally solve the problem instead of jumping on the Nissan Sucks bandwagon without any real cause is all I'm asking. I don't think heat alone is your problem. It's not a big enough factor to describe the catastrophe everyone's describing here. There's some other understandable fault here, one that can be isolated and remedied.

For the most part, this thread is a long list of people who apparently share similar symptoms, at least vaguely similar, and at least as a one-off event. That doesn't make for a shared defect on Nissan's part. Everyone needs to get to the bottom of their problem and see if there's a shared cause. Who knows what you'll find. Perhaps you'll find that 6% of all 370Z owners experience these symptoms, and over 90% of those reports end up having a root cause of a faulty sensor wire that comes loose too easily and screws up the ECU's behavior. Then you could come back and say "Nissan sucks, they can't make good sensor wire connections." Or it could turn out to be more like 2% of all users having this vague symptom, but the causes don't line up. You end up with 10 different causes. One of them's a few fluke sensor wires coming loose, a real defect. One's a dirty MAF sensor. One's a guy didn't realize one of his PCV hoses came loose after installing an aftermarket intake. Another had bad gas, etc. A large chunk of them didn't turn off VDC to test, even if you did.

You can't know until you do the investigation part. What this thread acts like now is more like a mob.

That's just it- owners shouldn't have to do an "investigation" over why this specific model of car produces specific issues in specific scenarios, especially if they just want to report an issue and see if someone else has experienced it. This issue is specific to the 370- even the 350 didn't experience it (as an owner of both cars with over 150k miles between the two- the 350z forums also don't have a similar thread) It's not a matter of VDC according to the posters here, but there is a common observation of ambient air temp being a possible issue.

Your observation that it may be a dirty MAF sensor, or loose wiring doesn't explain these observations. You suggesting it's a lack of torque "since 4 cylinders exhibit the problem" is nonsense. If you had truly felt this problem, where there's literally close to no power for several seconds before the car "surges" forward, you would understand.

While I appreciate your comments, it's not the place of the consumer to diagnose and fix a design flaw (if that's what this is). All we can do is report our issue and try to root out a common cause, which is what's going on- it's not a "mob", it's a group of owners who are frustrated by their cars exhibiting a hard to diagnose problem that goes beyond your "it's a v6 it doesn't have a lot of torque" diagnosis.
