I've got a bluemaxx 90mm tb that I ordered from vengence racing along with my ported 90mm FAST intake. Every time I give it gas after I installed it, it gets stuck open and will not go down unless I manually close it. When the motor isn't running, it's fine. I did the TPS relearn and fixed a small leak from the plastic fitting that's on there. I even took my intake off to check the gaskets and have checked everything possible. It's driving me crazy! Please help! Thanks!

 

easy fix, get a dremel or small die grinder. remove the wheel and slightly bevel the edges. this will allow it from sticking

 

What would cause it to do it only when it's running?

 

just a poor machining im guessing. my 90mm is the same way but it sticks at closed

 

YEAH I HAD SOME BBK THROTTLE BODIES DO THAT TO ME ON MY OLD TPI MOTOR... BASICALLY LIKE QUICK SAID JUST A QUICK PASS OVER THE EDGES WITH A DREMEL AND SHE'LL BE GOOD

 

I just got a message from a guy over at tech that said they had to replace his spring. Something about it not being strong enough to close it back against the vacuum. I'm just gonna send it back and get a Nick Williams. I shouldn't have listened to vengence and went with the bluemaxx.
