Well, I had to go and fix something that wasn't broke, that'll learn me...

Alas, I have adjusted the throttle screw, and now she runs like crap.

I know there's a way to adjust the throttle switch (on other side of intake, that leads to the ECU), but do I need an ohmmeter? or multimeter? Or is there some Zen master mind trick I can use to get the switch back in tune with the throttle?

And, I f I drive it like this (out of whack) will I damage the D-jet system any?

I would be greatful for any help. Just please be specific, as I'm still learning after a year and a half of vintage volvo enthusiasm. (My girlfriend and I are getting married nonetheless, she says I don't have to give up working on the car, but she said some things are going to change around here...god only knows what...I imagine instead of taking the whole weekend to work on the car I may only have a few hours...uh oh)

Cheers,
samuel
