i was looking at the hedmans and was wondering which one's to go with on my 305 tpi. footnote 5 says with A.I.R. Is this the oxygen sensor or the air injection system to the convertor or the smog system? my car had the cat taken off. i want to take off the smog pump and wanted to know if it would cause computer problems or cause it to run too rich or too lean? help is useful.

 

Removing the smog pump will not cause any problem with thw fuel mixture what so ever.

 

would it cause an error code to show when the sensors are disconnected?

 

no A.I.R is the smog pump and tubing that pumps air into the current exhaust manifolds, you can remove this without trouble and computer problems, but you must retain the o2 sensor.

 

I took off the pump and lines on mine and plugged my headers with the air system. I kept the O2 sensor of course but I noticed a difference in the smell of the exhaust. Smells like it is running richer but it isn't really. I have a air/fuel mix. gauge and I didn't notice a difference in it. I personally like the smell better. Just reminds me of old school.
