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?

bad MAF or AFM ? (quitelikely)
bad ECU (two wire) watch temp sensor
bad warm up switch, I can't remember the correct name for this sensor, it's basically a on/off water temp switch and it tells the ecu whether the car is warm or not. (extra fuel or not). older engines have this, yours might.
My 1992 Lexus ES300 intermitten skips like loss of ignition or fuel and check engine light comes on resulting in codes 32, 42, and 43. Clearing codes may run great for 30-40 miles before it does same thing again.
Can I get some help/suggestions on what might be happening?
