A few weeks ago I was cruising down the highway I could feel a slight stutter every now and then. It felt like when in turbulence behind a truck or a gust of wind hitting the car, but I wasn't behind a truck and it wasn't windy that day. I still wasn't 100% sure if it was the car, the road, or wind, but then it started to stutter when idling, almost at times I thought the engine was going to die while idling at a traffic light.
My CEL is already on because I need to replace my glow plug harness. I checked engine codes and I had a new one, P0183, indicating the fuel temperature sensor. I got an OEM replacement part, put it in yesterday, but it didn't fix the problem.
The other posts I found mentioned the wiring or a fuse. I just went out and checked wiring and I'm not finding anything wrong. The positive isn't shorted to ground. I started the engine and I'm reading a steady 4.96v at the connector. I let it idle and warm up until it began to idle rough. When the rough idle started, I unplugged it to check the voltage again, and as soon as I unplugged it, the idle smoothed right out. It was still showing 4.96 volts.
Since it runs fine with the sensor unplugged, what could this mean? What will happen running the car with the sensor unplugged until I get this figured out? What fuse do I need to check? I'm not seeing a fuse specific for the fuel temp sensor. What else could be causing this?
