All,

Once I get the car running for about 10 seconds, it starts running really rough. I presume it's one of the 3 sensors from back to front of engine block [2-pin sensor, 1-pin sensor and 3-pin sensor]. The 3-pin was recently replaced. Can anyone tell me what these sensors are? The 2-pin and 3-pin come up as coolant temperature sensors when I search for the part. My manual says the 2-pin is associated with the CIS. Any help would be appreciated. I'm almost inclined to replace the 2-pin at the very rear of the engine block to start off with.

Best Regards,
