Anyone drive a 350z after their 370z? The 350z feels so good as far as gas pedal goes....it does what its told....it puts the lotion on its skin.

Nope I would not go back to my 350. My buddy even has a newer 350 than I traded in and i still love the 370 more. Just gotta learn to drive It. It drives differently. However i am not experiencing the same problems as some others are

I had something interesting happen today, hopefully relevant. I was on my way back from the grocery store, and got a code. Hooked up my reader, it says "catalyst system efficiency below threshold". After talking to a couple people and reading online, consensus is that it's either O2 sensor(s) or catalytic converter. Since O2 sensors are directly related to fuel delivery, I hope there is a relationship to the throttle response problem. However, I have almost 40k miles, so I've passed the 36k warranty. So my guess is that they are going to say no, it's not a warranty fix. IF that's the case, F**K them, this car is GONE. No reason for EITHER of these to go bad with less than 100k miles.

At my autoX last week, the car was bogging badly off the line. I had to launch above 3k RPM and then the throttle/power was fine. But anything less, the car would fall flat on its face. Never had that happen before. Ambient temps were in the 60s and my IATs were between 90-140F.

Easy, federial law requires the maker Nissan to keep your car in emission standards for 50K. Dealers dont want you to know this, it includes cats, O2, and any codes related to them.

Give it a try, I had had friend get a new ECM after the car would not come out of limp home mode. Out of 36k warrenty (under 50K) but could not pass emmisions. Only snag may be the Florida has no state inspection.

That's what I see with everyday driving when it starts losing power off the line. I try to rev it past 3k RPM regardless of how much throttle input, but it has plenty of power down low to get moving when it doesn't exhibit this issue. I see you have an oil cooler, and it's not helping all? I still don't buy into this oil temperature being the reason for the power loss because it happens around 180-200F as well. [shrugs] BTW, is your ECU program stock?

Didn't know that, good to know and makes sense! And you're right in that FL doesn't have an inspection, but I'll try to push it. I already have an open record with Consumer Affairs too(not that THAT has helped much).

the catalyst code means that the change in chemical make up of the exhaust the computer is looking for between the pre cat sensors and the post cat sensors hasnt changed enough. This is usually a cat problem, but sometimes can be a sensor problem. Dealer diagnostics are usually required to get to the exact root of the problem. The 50k laws shouldnt matter between states because it is a federal law, i'd try that route.

You could always trade in for a 5.0 like everyone else seems to be doing!

Kastley85891 · 05-01-2011, 09:58 PM

It happened to me, first time in 9K miles, usual day,usual road, sucked

IcedZ · 05-03-2011, 10:47 AM

Dropped my car off this AM, just got a call. They said that the catalytic converter is bad! WTF?! This actually warrantied for 5 years / 80k miles. Still, a cat shouldn't go bad at 40k miles.

It shouldn't but sometimes it happens.

I'm still skeptical. We'll see though.

Like to see the Nissan tech enjoying cat removal
