2006 accord. Replaced compressor and condensor with new denso. Replaced expansion valve and 2 rubber hoses with 4 seasons. Pulled vacuum and it held overnight. Put one 12oz can of r134a and started the car. Low pressure side is nearing a constant 100psi. High pressure side is nearing a constant 150psi. I did not replace the condensor coil. Why low pressure so high?
