Hello I am Reggie and thanks for the question. This code, do you have a dead skip on cylinder 3 and do you suspect no spark as your problem. OR is the code settting and you are not seeing any running problems

Customer: replied 11 months ago.
it is running rough, I clear the code and it comes back on within 5-10 minutes of running
Expert:  Reggie Whiddon replied 11 months ago.

Okay we have a skip on 3. Are there any other codes? One problem i see with this system is and I know this is not what you want to hear is with the pcm this system does not have a ignition control module the pcm does the grounding of the coil on using drivers sometimes these fail and want pulse that coil. But we need to make sure spark is yuor problem. Do you have a compression gauge, spark tester or vacuum gauge??

Customer: replied 11 months ago.
no, we did put a new ground wire on the vehicle, this started after that.
