I didn't bend mine in half, I just laid 'em out & put a lead on each end. The only directions in the manual are to test 'em "complete with end connectors." And the manual's range for the plug wires should read "2000-4000," not "2000-3000" like I said earlier.
With your wires reading so low, I'd be tempted to replace 'em. But I'm not sure how much it'll help your idle problems. As long as you're doing all of this, clean up the electrical grounds as well. I think there's 5 or 6 in the engine compartment (top of the radiator, frame cross member at the base of the radiator, a couple on top of the engine, & a few around the alternator & the components in the left fender well) & several others throughout the car (parking brake, fuel tank area, one or two behind the dash maybe?).
Your plugs sound fine. I think the cooler 7s are the other option for your engine. My '90's not a turbo, so my choices are either the 6s like you've got, or the hotter 5s. I had been running the 6s, but since all my trips right now are short & infrequent (only 4k miles in the past year), I'm currently running the 5s. But I can't say I've noticed any drive-ability difference between the two.
I picked up my Bougicords from eEuroparts, but I wasn't really happy with the extra-long coil wire. I think they only stock one set for both 900s & 9000s. SobStory also carries 'em, & they might have 900-specific wires with a shorter coil lead. Both dealers are site sponsors, & both prices are pretty close.
The Bentley manual is the best thing to get for these cars. I think they're about $35 now (I paid about $50). I got mine from Amazon, but I think some of the site sponsors carry it as well.
