HELP! Mazda guys... engine isnt running right.
 

Its regarding a 1992 Mazda b2200 EFI 8v engine.

Once the engine is warmed up, the air/fuel meter goes to "LEAN" and about 5seconds later its running rough, sputtering out in a pulsating type condition. If I turn the ket off for a moment and back on, its good as new for another few minutes. The longer I turn the key off for, the longer/better it runs.

Here is what I have replaced due to the problem. maf, fuel pump, fuel filter, fpr, computer, coil pack, coil resistors, misc fuzes and relays and i'm sure I missed a few other things.

Ideas?? I dont get a CEL...

Looks like the new fuel pump already packed it in. Another reason why a vehicle should be left with a full tank over winter.
