Hey, I have a code coming up on my OBC that says "Catalyst".
It happens when I start the car and then it goes away, when I am driving sometime it will randomly come up when I let off the throttle.
The Car does Have Catalytic Converters, If I took them out and straight piped it but kept the muffler would that fix my problem?
The vehicle is a 1990 BMW 525i. For pictures look at my profile. It only has under 50,000KM, Maintenance has always been on time according to BMW and Motoralldata
