Installed NGK G-Power plugs and the misfire is gone. Really surprised with only 20k kms on the Bosch Platinum plugs because I've had OK results with them before. Thanks to all for the tips. If I notice any mileage improvements over the next month I'll repost. By the way, whoever it was at Subaru that thought 2" is enough space between the cylinder head and frame rail to change the plugs needs a beat down with a flex-head ratchet!

Dave, Thanks for the advice. I'll wait a bit for other bites and if not, go with the NGK plugs. I went with the the Bosch Platimums because I thought they would last a while and I wouldn't need to wrestle with another plug change on a boxer engine.......looks like that may not have panned out very well.

I'm located in Ajax, Ontario. Correction, I installed Bosch Platinum plugs with NGK wires and I have the 2.5L engine (Legacy Outback).

Hi, I have a 98 Legacy with 205kms on it and it's developed a misfire at idle which seems to even out at higher rpm. I suspect it's a plugwire though I can't see or feel any arcing from the coil or plug wires all the way down to the cylinder heads. I'm suspecting that one of the plugs is arcing inside the cylinder head. What's odd is that I installed NGK wires and plugs 20k kms ago so I'm a bit surprised it could be either already, and I have no DTCs. The reason I suspect this is because I had a Focus with a similar problem. One more strange thing is that I pulled the plug wires from the coil one by one to see if there was more/less change and cylinders 2, 3, and 4 seemed similar but when I pulled the #1 wire, the engine stalled - there seemed to be a lot more spark from the #1 terminal. Anyone else have any experiences like this?

You're right. The flange can be bolted up one of two ways (180 degrees apart). I've tried it both ways and I've got it to the lowest amount of vibration possible, but it still there and is pretty agravating.

Hello, I had to replace the rear section of the driveshaft on my '98 OB with one from a donor vehicle and I notice a bit of a vibration between 100-100 kmh. All u-joints seem ok. If I were to install the front section of the shaft from the same donor vehicle (I can get it for $40), and try to match up the flanges to get the phasing correct, would this get rid of the vibration? Are the front and rear sections balanced together from the factory? Thx.

Hello, I have a '98 Outback 2.5 automatic, and I need to replace the driveshaft (rear section) due to bad u-joints. Can anyone tell me if there are model years (other than '98) that would be compatible. Thanks.

Thanks, I actually hadn't noticed the post date. I'll check out the Rockford joints.

Pics of what you did to your driveshaft would be great if you get time!

Interested to know which Nissan joints wil fit a '98 outback. Thanks.
