INTERMITTENT STALL PROBLEM

1991 Mazda b2200 • 120 miles

Hello, I have 1991 Mazda B2200 w/ 120k miles. Runs perfect until it spudders, with raw gas smell from exhaust then stalls. Hot, cold, doesn't matter. Wait a while, then it runs perfect again. Always has spark and 37psi fuel, and DC pulses to injectors. Throttle position sensor checked good with ohm meter. No codes from ECU. ECU looks perfect (no leaking electrolytic caps). Any ideas?

Try cleaning the throttle plate iwth choke cleaner on both sides then check to see if your evap cannister is full of gas.
