1992 es300 running rich
running rich, removed ecu found leaking cap, repaired/replaced ran great for several weeks.
new plugs, rotor, cap & adjusted timing.
started running rich again, replaced ecu, ran great couple weeks. Found #4 plug wet with gas. Cleaned #2, 4, 6 fuel injectors. Ran good for test drive of 20 miles or so. Found all plugs black indicating all cylinders are flooding. Disconnected battery for couple days, once again ran great for 20 mile test drive. When restarted running rich once again.
can anyone help?
