So I got my 4wd protege running and driving (1990 5 speed with a BP swapped in)... except for one small detail...
It runs great when I first start it cold, if I give it 1/4 throttle it has plenty of power. If I put the pedal down it falls on its face, it will stall if I take out of gear and coast too. As soon as its warm it barely idles, maybe 300 rpm and dips to almost stalling.
I'm changing the fuel filter tomorrow, spark plugs, and cap and rotor.
The 4 wire O2 is new and wired correctly, I did a quick check for vac. leaks but didn't find any. Could my TPS be out of adjustment?
Is the stock BP VAF adjustable? It looks like someone had the cover off the one I have because it seems to have been re-sealed.
I replaced the ECU with another one I had and it ran the same.
Anything else that could be going on?
Also it seemed to be running rich at first.
