Highly suggest a stage 0 refresh - new plugs, wires, cap, rotor, and coil (use only Bosch - ask me how I know). It’s also not a bad idea to also replace the camshaft and crankshaft position sensor, as faulty ones can and do cause phantom misfires and/or misfire codes ok so I will be on the hunt for...

Go B4 for the shocks. Go H&R for lowered ride with better ride quality than stock. Reusing the factory coils is fine, but will be slightly stiffer. I do either Sachs or Lemforder top mounts

Get the 850 OBD2 app and a cheap Bluetooth OBD2 dongle and view live data for the ECC parameters. You should see pretty quickly what’s wrong. You can also try a new sun sensor, as well as a new ECC unit if you want to throw parts at it. I have both if you decide you want to try it, shoot me a PM Ho...

If it wasn't for the fuel tank nonsense and the lack of actual support for the AWD suspension stuff, I wouldn't mind having that instead of the Delta link set-up. I mean I do custom stuff all of the time for my cars anyway, but I have other projects to direct that energy towards. ( I would REALLY l...

After a run to the Pick-a-part for a few door lock mechanisms, I now have 2 ECC controllers. One is the 9134784 and the other is the 9171595. Both were pulled from 1998's. How does one test that they are actually functional? Put it in and give it a go - that’s about the best way. And correct, 98 EC...

I would match part numbers. I think wizechatmgr torched an ECC controller on a bad swap once I could see that with putting a 99+ module in a 98. Tried it and the car freaked out. However, the ECC I tried to diagnose my climate issues was a different part number (out of a part out 98 S70) and it wor...

I also use an ELM 327 el cheapo BT dongle for my '98. It's worth reading through my climate nightmare thread here: https://www.matthewsvolvosite.com/forums/viewtopic.php?t=102381 There's a ton of good info and diagnostic aid in that thread when I went through everything in my car to fix my own drive...

I’ve done a lot of:
- oil drain plug crush washers
- M8 lock nuts (strut top, exhaust manifold, etc)

I usually end up hitting free shipping anyway because my car ends up needing too much stuff lol

Big thank you Xanthefin for making this possible! Successfully programmed 2 remotes after obtaining the PIN through the app. It’s great to finally have remotes for this car after using the key in the door for over a year. I got some cheap knockoffs from eBay and they worked fine for those of you tha...
