Bump for an awesome how to.
I just cleaned mine yesterday, since my car was dipping rpms enough for the dash lights to come on every time I push the clutch in.
After doing this, my car is riding soo much better. It actually seemed to help with a few things.
1. On cold start, my car would bog badly at low rpm, like casually shifting 1st to second, my car would lurk back, and throttle response was badly delayed. This is now gone.
2. My car seems to be less sensitive to lurching back and forth when riding very slowly in 1st or 2nd(traffic jam style cruising).
3. Shifting and rev-matching seems easier than before, I was starting to think I was a bad driver becuase I couldn't drive this thing smoothly around town, but now I can rev-match again. I guess the rpms are more predicatble or something.
4. Strangely, the one thing it didn't fix was the idle dropping very low, although it may have helped slightly. I have many other mods done that could be to blame for this problem though.
It seems like their is much less drag from the engine when letting off the accelerator, this is probably what helped with points 2 & 3.
I'm hoping my mileage will go up a bit too, but we'll see. I've only taken it for a couple short drives since I did it. I'll keep posted on mileage gains if any.
