Had P0301, P0300 misfires come up on computer with strong odor of fuel, mostly at the front of the engine by motor mount.
recent work included full gasket/seal repair on upper and lower intake manifold with injector seals replaced, about 1 month ago. Also found vacuum hoses broken at the time of repair, which also were repaired. Also replaced plugs and wires with new.
This fuel odor just started tonight and noticed engine hesitate heavily under WOT and strong odor of fuel at the time. Did not see fuel leaking at injectors from my observation at point of strong odor by cylinder 1 and 4 (very front of motor by passenger side of car). LTFT is 7 at bank 1 and 9.3 at bank 2, with STFT between -1, 3 and 3%. Could the fuel leak be at the point of stronger odor point, or could it start, by the fuel regulator and travel toward the point of area where it is strong? Do smell fuel by regulator, but it is stronger elsewhere. Any ideas before the top of the engine is removed a second time?
have the same problem?
