Ok before somebody tells me to search... I have for 10hrs and nothing. I have a 1994 22re with 270k rebuilt at 200k and new parts in the last 5k miles are... plugs, wires, cap, rotor, fuel filter, air filter, ECM and fuel pump and I have a new O2 sensor coming tomorrow. So this thing when its cold I can go start it with not problems and when it gets up to temp (20 min in) it dies, It will start back up run for 2-3 sec and die again. It has a check engine light on that is flashing a 21 code and that is it. So that's why I cam putting a new O2 sensor in. I have my doubts that's what it is. I have read many threads like this one but my truck runs great until its warm. What would you guys think? I have checked the FPR and it has plenty of vacuum. Its starting to get to me.


Thanks
