...and I'm sure there's more I'm forgetting.
Most recently I did my PCV job, and during which I cleaned the MAF, fuel injectors, reran the vacuum lines with fresh hose, and replaced all the fuel injector seals. That PCV job is aweful for someone like me who has big hamfists. So I recruited my wife to help! Hahaha.
During that job I uncovered two new issues: the air intake thermostat is stuck on hot air, and that the car is equipped with VVIS. Yes, an American spec 1995 is equipped with VVIS. It is definitely stock. I have pics to prove it too. Hahaha.
So thermostat is now wedged into cold mode. And now I'm going to make sure that the VVIS system is actually functional.
Opening that cold air flap made a huge improvement in power and driveability. Now my car likes to cruise at 85 on the highway like my old wagon!
So I've put so much time and effort into fixing him, I think I'm just going to keep going and finish restoring him.
About Herman
1995 Volvo 850 Base, manual.
Green
185,000 miles presently
Vvis equipped.
Has no EGR and no SAS system
I run 10w-40 oil in it like I did in my previous 850.
Always run 93 octane (premium) and buy it from QuikTrip here in St. Louis (midwestern united states)
I'm going to take a look at the computer and see if he is running an LH 3.2 or a M4.2/3(?) system
He sat for two or three years when I got him so I've had to do a large amount of rubber replacement lol.
So why operation 30mpg?
It is multifold,
1: I see other guys getting 30+ MPG, so I gotta compete right?
2: I drive my car for a living so more MPG = more $ in my pocket every month.

What am I getting now? 22mpg. All the time, day or night, highway and city. So any suggestions as to where to start digging for those extra MPG? I delivery drive pizzas and we now have speed tracking software so I cant drive it hard even if I wanted to.
I remember on my old Civic that replacing the intake and exhaust systems with a more free flowing setup netted me a few extra MPG.
Maybe some weight reduction? Aero work? Talk sexy to him until he operates more effectively???? Hahaha
Edit: I have uploaded some photos for everyone's benefit.
Upcoming repairs: Heater Core, Thermostat, clearcoat on the passenger side fender, trouble shooting the PCV system.
