I don't have my O2 sensors in yet, they are plugged in and sitting on the strut towers in 21% oxygen.. what would that do to the engine? as far as how it runs? It seems to run a bit rough and when it warms up it runs at a low 300rpm idle. and after it gets a bit warm it take an extra sec to get it started again.. just wondering what the o2 would do to the computer, not being in the exhaust..
I understand that its all temporary until i get them in the exhaust.. but curious..

thanks.
