Friends,
After picking up my 2005 GS on Friday an putting 150 miles on it my check engine light came on. I reviewed several threads (thank you) and bought a code reader today. It showed a Warm Up Catalyst Efficiency Below Threshold reading. I cleared it and it has not come back on as of yet.
I assume it is because it was bitterly cold the past few days, highs in the low 20's.
Did I assume correct or should I be worried about the Cat? The car has 3,000 miles on it.
thanks
