decreased power loss of power

earthbound

Hello,
I'm experiencing power loss, when accelerating, over 3500 rpm ,
Has anyone had this problem , ambient air temp is not an issue,this is also happening when the car is not in sport mode, when in sport mode it's fine, performs properly

That's weird. I hope someone will jump in and help you out.

In the meantime, you might try cleaning the MAFs if you haven't done so recently. Very easy job - requires a screwdriver, some MAF cleaner, and about 15 minutes. Several threads on this site with instructions. Probably not your problem but, if it's been 9-10 years since they were clean, it needs to be done.

What is "sport" mode? You mean when SRM is on? Or what? The Z doesn't have a separate sport mode - it's always in sports mode

Probably not related, but I'll throw it into the hat.

Many years ago, I replace the stock air intakes with K&N Typhoons.
I screwed up the install.
I chipped off a very small piece of rubber on one of the vacuum hoses, which traveled up and lodged in the throttle body(?). Took it 2 weeks to materialize, but I was driving down the road when everything died.
Would barely hold idle, but wouldn't do much more than that.
That's my only suggestion.
Good luck.
