I previously asked the question listed below. We have checked the regulated pressure when engine is running and it is 33psi. When we check it without vacuum the pressure regulator reads 42psi. When we crimp off the return fuel line the fuel pressure jumps up, indicating it is not the fuel pump. We have put new plugs in, wires with distributor cap, rotor, fuel filter, fuel pressure regulator and even checked the timing, but we still have a lope or dead spot when idling and when you stomp on the gas, the engine bogs down to the point of not running or even dies. When we pulled the #1 plug out to check it, it showed signs of fuel running to RICH. This has us puzzled. What is going on? What do we do next?
Question previously asked:
I am needing to find out what is causing my car to have a DEAD SPOT when it is just idling? Also why did the fuel pressure drop when throttle pressed? Is it the fuel pump? What should the fuel pressure reading be with car running? I anxiously await your reply.
