there are a couple problems i have ran in to with my rx7.

First is i cant no locate were to plug that O2 sencer up to the wire harness.

second is that when i crank the car it take bout 20 secs to fire up and when it dos it revs to about 1200rpm and once i let go of the ignition it dies down.

Will the car not start with the o2 sencer not pluged in?

Thanks for the Help

 

There should be a green plastic single wire connector somewhere near upper right side of engine toward front. It can be hard to get at.

 

i know the connector u r talking about but the o2 sencer line is not long enouch to ge to the connector do i have to take the upper intake manifold/throttle body back off to give it enouch slake to get to the connector?
