I had codes for a cylinder misfire and running too lean. I then replace the spark plugs and wires along with the mass airflow sensor I cleared the check engine light and the code P1614 turn the check engine light back on. I can’t remember if that was one of the codes before but it doesn't look familiar.

This code is not going to be related to the misfire. This code is for the loss of communication with the RIM, radio interference module.

Is the vehicle still acting up like it has a misfire or running poorly? If not, then you will need to test voltages at the RIM to figure out what is missing. It is going to be power, ground, or the communication wires shown below.

Let me know if you have questions on this. Thanks

Well, I found out that the wire to my blower was damaged. But so far so good with the misfire.
