the air pump injects air into the exhaust gas stream causing the unburnt gases to reburn.  thusly lowering emissions.  If you have removed the dual flow exhaust down pipe etc and blocked off the inlet track into the inlet manifold.

thats a V simplified explanation btw.

take the bolts out


as explaind to me buy my tradesman an air pump only helps heat the cat up to the best opperatiing temperature we had an arnage in with a broken air pump and to get it past emmitios we just had to leave it runnign for a good 20 mins

Except that 2nd gens dont really have much of a CAT, they work by reburning the exhaust gases in the exhuast manifold...
