Rough idle then stall...please help
I recently cleaned the air filter on my cp-e intake about a week ago. Car ran great up until yesterday. Now it won't hold idle and eventually dies out. The only codes being thrown I believe are the p0171 and 4 for the down stream o2 sensors reading lean. I can drive the car around so long as I don't come to a complete stop or let the rpms drop below 1000. Acceleration is fine and has no hiccups. Car's exhaust seems to cut out pretty funny when decelerating in gear. I checked all my hoses and they are intact and sealed tight. I then pulled the IAC no.2 from the left side of the intake manifold/surge tank and the diaphram seems to be functioning properly/holds vacuum. I then replaced the vsv valve for IAC no.2 but still the same results. I haven't gotten gas recently so I don't think that would be issue and since the car's not leaning out at higher rpms/load I'm pretty sure the fuel delivery is not blocked.
If anyone can offer some advice I'm all ears. The only thing out of the ordinary under the hood visibly seems to be some crust from coolant on top of my radiator fan shroud under the upper coolant hose and level in the reservoir looks a little low. I'm heading out right now to pick up some coolant so hopefully that will do the trick, but I fail to see how coolant and idle would be related.
Thanks for your time.
