I'm looking for some info on why my 84 GTI seems to hiccup when accerating between 1000-2000 rpms. Past 2000 it's smooth sailing. I did find an old thread about a similar (if not the same) issue being fixed by changing the fuel filter. I'm going to try and change that this week, and try some fuel injector cleaner. Are there any other suggestions on what the problem might be and how to fix it?

Thanks,
