new O2 sensors now running way to rich

[88fivepointoh]

well, obviously something went wrong there.. what brand are the o2's sensors? the universals however won't work at all.. get the specific sensor for the car and in that case, it doesn't hurt to get ones for the mass air'd cars 89-93 5.0 to better fit the computer.. some manufactures have different part numbers for those cars. autozone, advanced auto etc etc sensors are ok, but u will see a slight better performance and it really is noticable on the dyno with Ford OE sensors. but get those universals out of there and get the right ones for the car. hopefully u can return then. they should cost 40bucks each. let me know how it works.
