Question about 1995 Dodge Dakota
Hi my 95 dakota 2.5L stalls after its warmed up.it will start up fine when its cold idles and revs fine, and i can drive it for a short time then the engine shuts down with no sputtering just stops running,and will not start until its had time to sit for an hour or two. when i try coding it comes up as 2,7 which Haynes said it was fuel circuit control, and 5,2 oxygen sensor stuck in rich position. when it dose die it spits fuel up out of the tbi, and it usually stalls while i am on the gas. my question is if the 02 sensor can cause the engine to stop running if its **** in the rich Position.
Yes it can but you may have a coolant temp sensor acting up which causes the computer to open the injectors to much which can also cause this 02 sensor code. when it stalls do u have spark and fuel pressure.

Engine stalls or RPM
fluctuates at idle up and down or dies near idle.
This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve but always run a OBD2 fault code as well as the cleaning procedure. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control
