Question about the o2's. I just swapped out headers. Reset idle and tps. but car drives like crap. the o2's arent in yet, I have to drill the holes out for them. Would they cause it not to have power..meaning whe i tried to driv eit, man it would kind of rev like the tranny was broke, would get up to speed ok, not great.. so I am basically running with out maf so it will drive ok..

Yes, O2 sensors are crucial. They are what provide the feedback to the computer on what fuel trims to use. If you don't have them the computer knows nothing about what adjustments it needs to make

Having the O2's missing completely is worse than having one malfunction but still provide readings. You're car is basically in limp mode and the enginer parameters are designed to protect the engine from detroying itself until you fix the problem.


Install some good O2's (rockauto.com sells ford O2's for cheap), reset the computer and basically start from scratch. Read the codes and then go from there. One thing at a time, and right now #1 is O2 sensors
