I'm thinking that the air pump being disconnected like that was just an added problem.. I'm worried that it might just be covering up the issue.. I don't understand how that would have gotten worse and worse ya know...
and the whole cat getting fucked up thing isn't a direct issue. The cat gets clogged up because the 5th and 6th ports are open all the time, which means there is actually too much fuel in the lower RPMs. therefore, there is fuel in the exhaust which in turn burns up the cat. the air pump actually just heats the cat up quicker so it starts to work sooner...
yes and no
with the air pump disconnected the ports stay closed unless wired open
the air being pumped into the cat does heat it up but more importantly it does this by providing the exhaust gasses with some air to further combust
also the VDI system is very very very important to performance for this car - think of it being like variable valve timing only not really
norachelhere I don't want you to think I'm bashing on you please, (cuz I'm not, you've asked some really good questions)
these are interesting little engines and it's not just the spinning triangle that you have to wrap your head around to understand
they have alot of strengths and some definite weaknesses
so have some fun and keep readin
