2002 V6 Camry - Faulty VSV valve. Hard to replace?

[birdie]

I was having troubles with my car surging, and running generally rough at idle and not under load... (like going down a rise). It was fine under power though...

Now I had my car serviced at Toyota today, and they found a couple of vacuum hoses disconnected, and one had to be glued back onto the air-box... it explains the problem now that it was to do with vacuum and reason why it was fine under power...

Now they also said the VSV valve was faulty (which I googled and found to be vacuum switching valve)... Now they quoted me $515 to get the part from Sydney and replace it (so labour and parts)... now I got a price for the part is only about $155 and I can get it cheaper again through my dad's trade account at Toyota.

So I'm wondering why its so expensive to fit the VSV... is it really time consuming or hard? Or is it a job my dad and I could do? (dad used to do a lot of the mechanical work on their cars, utes, and tractors when we lived on the farm...)

The part number is: 90910-12174

The car is a 2002 Camry Sportivo, 1MZFE V6 Manual...

2 thin vacuum lines and a power connector. It sits under the engine cover.

Doesn't look particularly difficult
