2001 Taurus misfiring in idle?

[daltomare]

I am currently having the same problem with my 2000 LX. I am getting code P0300. I actually stalled out a couple of times when sitting at a stop light. I was advised to change plugs and wires but I dont want to do this work and it be something else. Any suggestions? Or should I just stick with changing the plugs and wires. I also have been getting code P0457 and have changed the gas cap 3 times.

Getting the cylinder 1 misfire code as well. Random shaking at idle. I replaced all plugs and all wires. Still have the shaking. Have not been able to get the code to come up yet but haven't really ran it since it was shaking.

Could the coil be a problem on just 1 cylinder?
195k miles. Ran perfect until now, Owned since about 10k miles. Maintenance was done on time and properly.

I was thinking coil next but if it is more serious I don't want to throw more money at this.

I suppose a compression test would say for sure. Kinda a pain to get to the 1-3 cylinders. What fuse # to pull to kill the injectors/fuel pump?

TIA

Yes, a faulty coil can cause a single cylinder misfire. Check the cyl. drop test video on here. You can also run primary and secondary resistance tests on the coil.
