[s-cars] Fault code 2341 continues

Mon Sep 13 13:15:58 EDT 2004

Mike,

If it's doing it at idle, then start disconnecting injectors one at a time
to find out which cylinder doesn't make the engine run worse when its
injector is unplugged.  Hopefully it will be a bad channel on the POS/PSO in
which case you get one free fix.

>From what I've seen coils don't usually present themselves as problems at
idle, which is why it's a bit more of a PITA to figure out which one is
causing the problem.

Bob
