...but when you switch the a/c on the tickover rises by about 200rpm, and vice versa....
Re smells, I'm pleased to say I dont have those issues!!! Seriously, I dont like running ac all year round as it makes the air too dry and chilly, even at higher temps, in the winter....never had to get a system regassed yet and I usually have my cars for at least 3 years.....
