...like the o2 extender? canadian tire [an automotive store] didnt have any, nor could they help me locate even those spark-plug defouler things.

i want a new 02 sensor and so far ive been quoted 114 bucks for one, is that typical or can they be had for a lot less?...

i also cant locate one of those 'add-a-fuse' things, nor figure out how to wire this contraption through the ignition system [another issue but if you have an answer please tell me]

...cant find an amp meter for mounting on the dash...

...cant find drain cleaner with KOH, i guess there are different dominating brands in canada then the USA, we just have ZEP! in home depot
