Hi folks. Been getting horrible gas mileage on my new to me 96 2.8L and from what I've read, the general consensus is that a bad O2 could be the culprit. For year 96 models , how many sensors are there? Is it 1 pre cat and 1 after? Or otherwise? Where do you guys source your parts in the GTA other than the stealership?

Input appreciated..

there are 4 one pre cat one post cat and 2 catalytic converters. GL spending a grand on new ones. if they are shot and you ignore them long enough the cats usually go with them. I just replaced all mine with magnaflows if yours are rattling to bits replace them
