So I should be alright with 98 PCM and no rear 02 sensor?
I'm getting the exhaust done tomorrow morning, and wondering whether to have a rear 02 bung and sensor installed or not...
advantages/disadvantages?
98 PCM running 98 programming you should have no problems with a missing rear O2 sensor. BUT, you might want to install a rear O2 bung for a wideband down the road just in case.
