01 21v limp mode?

[SONIC]

Check your trans fluid as well. Just a though but 3krpms and 15mph seems off to me, maybe your trans is slipping.

It does. I called glide seal and he asked me the length I needed. Mine is the original so it's not apples to apples. I'm upgrading mine as well. Thank you!

Did you get this fixed ? My 2000 2300v is doing just this. Replaced water separator, cap and rotor. Runs fine in neutral, and with a fake a lake. But in the water. It's literally this same issue. Please help

I Agree with boatwakes except you may only have one Pump. you might not have the boost pump.
