I think there's a tech note someplace that talks about checking both EGT thermocouples. Kind of like the tail ligt warning system, the EGT system compares the two sensors, and shuts down a bank of injectors based on difference between the two. I'd start out reading millivolts from the two sensors at the controller/relay end and comparing, and even then I'd only replace the TC's in pairs.
Just a thought!

John,
How would I bypass the relay? Is it possible The ezk relay or the computers (lh or ezk) could be causing this? I also replaced the eprom in the ezk with factory chip-took out an autothority set. Any thoughts are greatly appreciated.
Thanks,
