Put new O2 sensor in (rockauto NTK).
New sparkplugs RC12ECC (been running on RC12LYC previously).
Also put in a new blower motor resistor - yay! Variable speed aircon!

Now just need to figure out while it's still running rough on idle and sometimes around 1800rpm taking off.
I'm guessing it's either my loose distributor or maybe the TPS which seems to throw random readings at idle and under part throttle according to my scangauge 2.
