I have a 95 Z34 and it had the Cat deleted. DOnt see any codes as of yet. I am going to be modding regularly so trading here a lot saving some $ and fixing the idling problem first and body next then performance mods. The cat delete question did tell me some sensor things i wanted to know about thanks guys..

 

Odd- did the obd 1.5's not have a rear O2? If there is one, I bet the code is coming with time.
