Guest FBody Addict Posted August 4, 2004 Report Share Posted August 4, 2004 Would the air pump removed cause the O2 sensor to get a bad reading and cause it to run lean or rich and cause it to backfire? yes, im asking about the 86 t/a once again 305 TPI Quote Link to comment Share on other sites More sharing options...
Dave1647545494 Posted August 4, 2004 Report Share Posted August 4, 2004 not as long as you have everything removed and capped off correctly air injection is after the o2 and helps the cat stay hotter for emisson purposes only. Quote Link to comment Share on other sites More sharing options...
Guest FBody Addict Posted August 4, 2004 Report Share Posted August 4, 2004 the injection is right at the heads above the O2 sensor and into the cat (which a previous owner raped with a coathanger) lines capped, maybe a vacuum leak? any other ideas?
