[ba] 5 cylinder won't idle after changing out oxygen sensor

[Michael Heth]

Say Folks,

The old Coupe failed to pass smog so I did a tune up (rotor, cap, plugs, air filter).

Ran a good bit better but I wanted to also change out the oxygen sensor since it had been a few years.

Did that today, but now it is harder to start and will not idle.

I have to keep some pressure on the pedal and keep it above 1000 rpm.

Engine revs fine.

I assume it just got leaned way out.

Tried turning the idle screw in the manifold but it did nothing.

While changing out the sensor I had to remove the intake boot and found some muck in the top of the big aluminum air body with the circular plate that depresses.

To clean the muck out I did push down on it but assumed it would find it's correct position once the engine was started.

Any clues greatly appreciated. I have been able to misplace both my manuals (looking for them right now).

Thanks,

M./
