Can a faulty or ungrounded radio cause a p0351 diagnostic code?

Question

My 1996 Jeep Grand Cherokee was idling rough and stalling with a loss of power.  Took it in for diagnostics and got a p0351 code.
The shop saw that I had a new ignition coil and concluded that I had a faulty PCM.  Before I could get the PCM replaced the car stalled again and when I restarted it the radio loss power.  The car is no longer idling rough and it hasn't stalled or cut off since.
The fuse for the radio  was not blown but I am hesitant to put another radio in. Should I replace the radio?

Answer 1

P0351 Ignition coil 1 primary circuit

You can replace the Radio , but this code that set P0351 (primary / secondary ignition failure). has a separate ground and even the ECM has a separate ground. from the radio. The worse scenario for P0351 is a ECM. Without jumping to conclusion this code can be set if you did not seat the ignition wire to sparkplug , or and this is common the use of excessive dielectric grease or what I call the tune grease on the sparkplug to ignition wire.
