the DTC error is not ever good. even 1 second long , nasty limphome goes in to effect.
all spark advance ends (you saw it) it is not a surprise this at all.
idle speed controls are suspended.
engine goes super rich and fouls spark plugs
burns up the CAT easy.
15MPG fuel usage (horrid) only if DTC holds solid fail.
89-95 were the worse, rich as pig fueling,. if cat is not there (missing or roddedout) see black smoke huge at tail pipe end.
96+ far far better, same rules but not anywhere near as bad. effects. (EPC knew all this and forced a correction, 1996 OBD2 et al....)
LIMPHOME mode is never fun. it is only for making car drive home, and not get stalled in the woods. or in snow drifts, etc..
