mk2? How was it running before you changed gasoline quality? What kind of injector cleaner and how much of it was mixed with how much gasoline? What's the gas octane level? How are your chain and sprockets?
- mk2 = 2010 model
- Running fine before I changed gasoline. And I did 4 or 5 tanks with the new
gasoline, before this issue came up.
- Did 2 tanks with STP Injector Cleaner when I changed gasoline. I added, as I recall, 80ml to each full tank. Following the instructions, I think this is (about) the right amount.
- Sorry, wasn't too specific on the gasoline scenario... Here in Portugal (all over Europe?) we only have 2 types of gasoline, 95 and 98 octane... We have the normal and the low-cost gas stations that sell both. As I understand (could be wrong), normal or low-cost the gasoline is the same (in quality, not in octanes), the difference is in the additives they add to the gasoline (or not) in each gas station... I was running on low-cost 95, changed to normal 95.
- Chain and sprockets seem fine, but maybe it's time to change!?... 23K miles on them already
If you do go digging around maybe check to see if the air filter was oiled way too much by mistake?
Good point there
... I did the air filter clean/oil myself (changed the plugs at the same time also) and that could be the cause of the problem... But this was done 6K miles ago, wouldn't the problem manifest itself immediately after the air filter clean/oil?... I really don't know...
Thanks for your feedback.
