have a code P0300 on my car and need to find out how to correct the problem. checked fuel preassure with 38psi with key at on position 34psi with car running. replaced fuel filter and cleaned screen on bottom of fuel pump. found replacment fuel line clip and did fuel preassure check again. got 52-54psi with key at on position but drops down to 34-36 psi with car running. any thoughts what my next step should be?
