My car is idling rough. It stalls out when coming to a stop, and if it doesn't stall, it idles up to 2000 and then back to <850 and repeats. Or it will just die. That's if I have the air /heater running. If I don't, it will idle normal, and then die. No idling up. I've changed the O2 sensor, because it was tripping code P0171, changed the idle air control valve, and replaced the valve cover gasket due to oil leak. I also cleaned the MAF sensor. We've continually thrown parts at it, and don't know what to do from here. Everything we've changed has needed to be changed, but nothing has solved the problem. Any advice would be amazing. Don't know where to go from here. The check engine light is no longer on, but the problem hasn't improved.
