Nissan 370Z
Rear-drive VQ coupé, and the two generations behave differently enough to be worth separating. The 350Z's VQ35DE is the one with the oil-consumption reputation, and on early cars that consumption is what eventually kills the catalysts and produces efficiency codes — treating the code without measuring consumption gets the car back. The 370Z's VQ37VHR adds variable valve event and lift on the intake side, so a timing or lift fault there produces codes the earlier engine cannot set. Both use a clutch-delay and rev-matching arrangement on the manual whose sensors generate their own faults. The CSC clutch slave cylinder inside the bellhousing is the most common non-engine complaint on either.

Service information
Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
