The CVVT job — burn off environmentally bad gasses produced in the first minute or so from a cold engine. CVVT technology superseded fussy air pumps after it matured enough to be a dependable component of passenger cars. See Wikipedia’s CVVT page. See MVS’s how to change the CVVT hub on P2 Volvos. See all […]
Emissions testing: required for all Volvos made after the last ice age, right? Not for some 1993-2000 FWD/AWD Volvos. Volvo’s emission standards were too high on the P80 Volvos. Yes, too high. SonicAdventure: I have a 98 non turbo V70. Build date is 5/97. When I called the local Volvo dealer they said that my VIN […]
Longtime MVS Contributor Neil is looking for a XC90, first generation. But which XC90 to buy? There were no fewer than four engines used in the first generation XC90, which ran 2003-2015. The problem? The five-cylinder XC90 hasn’t been made for over a decade. He wants to find a 2003-2006 five-cylinder XC90 for power and durability, and […]
MVS Forums Moderator abscate made an interesting post about OBD-II readiness states during state smog emissions testing. It turns out that recently (2015 for California) some states have relaxed their rules about passing/failing cars without all monitors in the readiness state. Yes, this is technical nerdery that can cause you (or used to cause you) […]

Interested in the famous VVIS install on your non-turbo 850? MVS super contributor Neil shows us how he did it back in 2012. Availability of this VVIS mod is not certain, let’s start there. Another important fact is that it works on 1993 and 1994 N/A 20-valve 5-cylinder Volvos, unless you want to look at […]

MVS Contributor Eric aka deepsouth posts a DIY tutorial on replacing the evap J-hose on a 2001 XC-70, including photos: “Recently changed the evap J-Hose on a 2001 Volvo XC70 AWD. I’ve changed evap hoses on all forms of S/V70’s and 850’s but this was a new form of hell. The charcoal canister is above the rear […]
MSD 8207 Blaster Ignition Coil installation photos from when I put this on my 1997 Volvo 850 T-5. There’s no gotchas or complexity here. If you can turn a wrench you can do this. This MSD has worked fine, no complaints at all. It’s a solid part of any Stage 0.
I’m a little bit of a number geek and like to know what is going on with certain things all the time. So I decided to purchase one of the Scan Gauge II code scanner, etc., from iPd. Yes you can get them from other places, I just like to do business with companies that support us Volvo owners. So I purchased one in July 2009. My primary reason was to have a trip computer in my ’97 960.
I was so busy traveling, working, etc., that the thing sat in the box for about 6 weeks. Eeeekkkk! So much for the 30 day money back warranty. Anyway, I finally opened the box and hooked it up to my 960. My main goal was to check my fuel consumption. I’d like to know what kind of gas milage I’m getting, especially at $3.75 per gallon for 93 octane . Pluged it in and it fired right up. It took about 20 seconds to sync with my ECU but I was ready to start playing then. The 1st thing I did was check my CEL. Ah, P0330, misfire #3, it reset the code in seconds.
