OK team....I don't know much about throttle bodies. Dealership said that the CEL code they got this time and last time I brought it in points to throttle body.

They said that they both need to be replaced at the same time per Nissan's maintenance instructions.

Some here might suggest I buy aftermarket and do it myself etc, but I'm just not going to do that. I'd like advice on this dealership's recommendation.

Info/Questions:
1. Do we really have two throttle bodies in the 370Z?
2. Do I follow their lead that they need to both be swapped out at the same time?
3. They're quoting me $2186 for parts and labor (2 TB's, a gasket or two, and 2-3 hours labor)

Bottom line:
Does this sound reasonable for someone like me with no other access to tools to go along with? If so, thanks. If not, what are my alternatives?

Background: They 'cleaned' the throttle body last time I believe and reset the light. It came back. It comes back on car startup. Low idle and sometimes stalls on after starting up unless I rev a bit, then it just idles low. Those are the symptoms I experienced.

Do we really have two throttle bodies in the 370Z

Actually Boch has them for $491.87 left/right each. Just an FYI. Hope all works out.

Before you ask the G37 is the same exact set up as the 370z and procedure to clean the throttle bodies. Do it yourself for essentially nothing.....then see if the light comes on. I do not believe that you have throttle body failure...they are just going to rip them both out and put new ones to get your money.

Find another shop, have the exhaust leak addressed first. that could be you problem depending if its before the Oxy sensor. than go from there. With 83,000 miles could be a vacuum leak., or something as simple as that.

I will finally grab it from the dealership today and bring it to a place my landlord recommended locally for the exhaust leak. The dealership got to do my synthetic oil change and will get their diagnostic fee. $120 total

I agree that the throttle body might not even be the reason for the CEL and that both probably don’t need to be changed at the same time. One or the other.

I’ll make a new thread once I get the car back and see the OBD-II code. Thanks all
