Whats up HT I have recently swapped a LS Turbo in my 2000 Integra. Motor started right up, and runs. We bled the coolant and it doesn't seem like the thermostat is opening. My car drives after you get past two step. When the car is just idling it bounces of the two step. Any ideas what this could be caused from, my dynotune is tomorrow and I just hope i can solve this problem before i have to get to the shop. Thanks, P.S. Here's a list of my build.

vacuum leak somewhere...

 

Checked all the lines. Any lines in particular that might be causing it?

 

Do you think it could be in the tune?

 

doubt it... check again for vacuum leaks at TB and intake gaskets.
