I recently did a motor swap in my 91 hatch and everything went well. Wiring,Axels,etc.. My car runs well and did for two months. Now my question is recently my car from a cold start bogs down when i give a little gas, but it runs well when warmed up. From a warm start the car starts well. The car runs great its just that part of the start up.. Any thoughts.. please help.. i checked all wiring..
