Yes, plugs are fairly new and after playing with the motor a little i have found that if i make a vacuum leak the engine runs a little better which makes sense because of how rich its running. I checked the injectors and they dont seem to be stuck open so when i pull the fuel pump fuse the car runs perfect for about a minuet unit there is no fuel. I put a clamp on the fuel line right after the filter and the car idles better. Could this be a vacuum leak to the fpr or the fpr it's self? I do know that the prior owner installed a bigger fuel pump and i fixed a fuel leak at the filter a few weeks ago.
