I have a 94 gsr throttlebody on a 1st gen b16a ITM in my ls/vtec. I had to fill in an air leak after installing the TB because the gsr TB had a slightly diff shap where it matted up to the ITM. The car boggs vary badly at times like the Map sensor is sending weird signals to the Ecu. could this TB be causing the prob? any help would be awsome! thanks

 

it's bogging because the MAP sensor is throwing the ECU into limp mode and can't tell what the exact pressure is inside the intake manifold.

make sure your MAP vacuum lines are right, as well as detecting the proper vacuum from the throttle body to the MAP sensor.

If you have done that, then I would switch back to the B16 TB

 

when a honda engine runs in limp mode, will it throw a CEL?
