Filter makes no difference TBF unless you're driving through rocks, sandstorms etc. It mearly filters crap/restricts airflow, which the ECU compensates for.
Now, what really might make the difference is....reading the stickies (at the top of this section), which do ask you to post the year of donor engine
I know you posted the ECu number etc but it ain't worth bobbins with Scoobies
Engine, Donor and year.
You might owe me a "slab" and JP (well it's his site) some cookies after.
I'm negotiable on "slabs" - "Lava java" and "Morgan's Spiced" _________________ The advice you receive on here is worth the paper it's written on.
Your experiences are worth shed loads to others, including the f'ups - live and learn.
Wouldn't YOU rather learn by someone else's mistakes? So would they.

The hunting idle is a really common problem, it's the Idle Control Valve needing a good clean out.
They gum up with crap and start doing that.
The back firing on over run is probably also related, if the ICV isn't shutting properly on over run you will get the popping and back firing.
Also a muffler leak or just a muffler system that is just too free flowing can cause it too. _________________ 1974 1303 Germanlook Suba-Beetle
