Stalls and starts right up, mostly when its warmed up, when it stalls\sputters it smells rich, sometimes I can pedal it to keep it running but mostly it dies, I can smell the rich exhaust through the leaky manifolds, driving me nuts, I changed the map sensor, pip and tfi, cleaned the air valve, there is no cel or codes other than vane air flow meter missing or out of range. Would tps act like this? I even went around shaking wires to see if anything is loose.
