Why don't Volvos like the Iridium plugs?

Put in OEM Volvo spark plugs (the pack of five) or just the cheap copper Bosch or NGK properly gapped.
You may be looking at another fuel pump and fuel filter too, cheap compared to what is "downstream." Siphon the tank as empty as possible. You'll want to put the rear on jackstands and have a board distributing the weight of a jack snugged under the plastic tank before removing the three bolts for two straps. Don't cross-thread them when reinstalling. The tank is HDPE (#2) if I remember correctly, but I doubt you want to go down that road. 
No. Avoid coppers trying to save a buck or two as they won't last as long, Bosch won't warranty them and they cost more in the long run (replacements per 100k, labor, plug wire stress at change). The OEM plugs DO have iridium (Bosch FR7DPP+, an "OE Specialty" plug, not an off-the-shelf type), albeit a platinum-iridium alloy. Any parts store that doesn't stock them can order them in (see the link). Run what you have 'til bad* then switch.misha wrote:Put in OEM Volvo spark plugs (the pack of five) or just the cheap copper Bosch or NGK properly gapped.Duake wrote:...New Iridium spark plugs put in about 3 months ago.

I think I might be able to open it up again this weekend so I can get that junk out. I don't know if I'll be able to maneuver it around the plastic circular levels, but I'll try.abscate wrote:Pull some and put in a Baggie and send to me.

I actually get gas from multiple places, so I don't think that's the problem. I always use 89 octane when I fill up. I've used Octane Boost a couple times, but I don't know if that really does anything.rmmagow wrote:I'm not familiar with the gas tank on a GLT but if doable, I'd pull it out and have it professionally flushed clean. Something's really not right there. A long shot, but do you always get gas at the same place? I'm wondering if maybe you got a load from the bottom of their tank. For a time, try a new station, one that gets a lot of business. Be sure to use at least mid grade and fill the tank.
