I just swapped a B16A1 into my 90 Integra LS. The new engine had a cracked TPS so I replaced it with one I sourced from a junk yard. I can't get any power out of the car. It revs slow and does get enough power to drive down the road. It does idle fine. I need help. Thanks.

 

If you still ahve your original motor sitting around, use the throttle body off of that.
