High idle RPM after hard buoy riding?

[skigolfnut]

Sometimes when I practice some buoys for a hard 30 minutes, the idle stays up at about 2200 rpm when I stop,
I have to shut the ski off, and then after the restart it is fine, like normal,

I can ride easy and slow and no problems with the idle, only after riding hard, it acts up 1 out of every 5 times,
any ideas?

a vaccume leak is a good start
then check the idle circuit

[skoepp]

Vacumn leak at the manifold will do that.
Pull your manifold and inspect.

Also check to make sure your TB blade it closing all the way. Salt corrosion can make it stick too.

thanks, I will check tomorrow

What RRFPR are you using?

[haapiti007]

I have the same issue too. Idle raises around 2300 RPM when engine starts. I have reset the TB with candoo pro but still not working. I use riva rrfpr

[skigolfnut]

I am using a cheap rrfpr, I did notice the O ring that seals the adjustment nut on the rrfpr was split in two and sticking out,
I will inspect for other vacume leaks,

The O-ring is not required and can be tossed.

thanks beerdart,
darn, I thought that was it, now back to the drawing board,

Cheap FPR = boom. I learned to use Aeromotive after my first boom. The other guy probably has a TPS or IAV issue. If your IAV is getting stuck then it would cause that. A lot of IAV issues on this forum lately.

Whats your fuel load when it happens.

[skigolfnut]

I dont know? next time out I will check it out,
I had the RRFPR dialed up pretty high while I was testing a new ECU, I will also look down the throttle body to check it out,
