o2 sensor question

da89cup · 08-09-2006, 11:39 PM

Do I need more than one oxygen sensor if I don't have any cats. On my old engine, I had headman headers on it & it only had one threaded hole for the O2. I'm building a 358W EFI & I bought 1 3/4 MAC equal length long tubes & each header has a threaded hole. Can I plug one up or do I need an O2 for each side? thanks

the EEC from a Mustang is going to look for two O2 sensors and throw codes if they are not there. It's best to run two anyway.
