Hey,
thanks for the detailed reply...
well, it seems like it did make a big difference, having the injector fluid
in and all that...
( come to think of it, last time i changed the oil the guy at Walmart
reassured me they cleaned the injector
but it made no freaking difference, i probably got ripped off, heheh )...
well, i live in Quebec so it's definitely not the right part of Canada (
just kidding ), but i travel to Toronto way too often these days, gotta
maintain that damn civic..
