Re: What did you do to your truck today? Chapter II
Drove it. I've been having issues with the truck shutting down. Surprisingly, it is RPM noise from the MSD ignition box affecting the pickup wire for the FiTech efi system. I tore my wiring harness apart, separated the wiring between the efi and ignition and now it's running well again. Very interesting but frustrating too.
