I have a 2003 Roadking Injected with 13k on it. I recently installed true duals and put on a PCIII. No problems for 1k and suddenly seems to be running very rich and bogs down/misfires under load. Worse when it is cold. I pulled the plugs and were a little black but I wouldnt consider them fouled. Replaced anyway. I disconnected the PCIII and no improvement. I ran the diagnostics and if I did it right I showed a code 32 but only once and not again. The service manual covers alot of items that could cause this. Any suggestions on likely culprits before I start replacing a ton of electronics? Thanks!
