I have a 2004 Outback and about 6 months ago I noticed that there was no pressure release when I opened my gas tank. Thinking the gas cap had lost its seal, I replaced it with a Subaru parts cap, but that did not solve the problem.
Shortly after that the Check Engine Light came on. After driving with the light on, it went off and stayed off for a few weeks. I took it to the dealer and they ran a diagnostic and said the Catalytic Converter was running intermittently and that it should be replaced. $2500.00
It has now been at least 6 months and the light comes on for a short time and then it goes off for a longer time.
Could it be oxygen sensors? - any suggestions. There is no loss of power when the light comes on. The car has about 130,000 miles on it.
Thanks,
Anna
