Question about 2002 Chevrolet Express
My 2002 Chevrolet Express service van has poor air flow from the air conditioner, probably because of a clogged filter. Where is the air conditioner filter located? Thanks, Harry

Your numbers aren't that far off...the mpg posted is established using professional drivers...I could likely coax a few more mpg out of your car if I drove it because I know how. Generally, today's new engines do not need any "break in" so it should have adequate power right out of the box! There may not be any updates for the computer, but the map sensor should be able to compensate for altitude changes. Using a synthetic oil can help a bit as well.
I'd try and find out if there were any optional transmission or final drive gear options offered for different localities. That may affect both mpg and performance. As for shifting, (as well as everything else you mentioned, I'd definitely contact factory customer service if you aren't getting anywhere with your dealer) The car didn't cost $5.00, and therefore I would take it to the "next level" if you aren't happy with it!!

This may be one or two different problems. One could be the climate control unit itself. Surprisingly the problem with the air not changing the source will likely be remedied by a reprogramming by a Volvo dealer. Defrost is the delfault outlet if there is a problem with that system. As for the dial not having detents and the cold instead of hot air in the pass side, that could be programming, a disconnect with the heater door for the passenger side or it could be the control unit. 98 is a difficult year to diagnose and the dealer is likely the only one who can properly diagnose this car. The download at the dealer is an inexpensive fix. If there is a mechanical problem within the air system that could prove more costly. I'm not sure how much the control unit for the climate control system, but there are usually quite a few on ebay. Good luck and I would suggest visiting the dealer first for this one as it is the least expensive fix and could very well be the only problem.

on some GMC models there is a valve that opens when you turn on the heat inside. It is called a heater control / actuator valve, it works off engine vacuum thru hoses connected under the dash, and going to the top of the valve. Now junk and crud and old rust will get in the valve and restrict it's flow. You will have to pull the valve off and clean it, but it is best to replace it, seeing it is hard to get all the junk out of it.
It looks like a L shape pipe with a hose on top & bottom, black plastic,and a smaller line on top mounted close to the wheel well about even with the exhaust manifold on the pass side. Drain the coolant, remove the valve and see if this is the cause, lots of gunk in the one hose. It is not real hard not real easy to replace this valve. Now if your truck does not have this valve check the pipe that the hose hooks to on top of the engine, remove the hose and see if a small screw driver will go down inside or if it is stopped up. .

I also have a Chevy Captiva 2L Diesel but with the auto box. The MPG on that one is abysmally bad! I bought it a few weeks ago with just under 30K miles on the clock (2007 model), and it returns around 230 miles on a full tank! That's around 17 MPG and probably on par with a Hummer!!
I was expecting the auto box to be less efficient than the manual of course but not to consume twice as much. Anyone out there with any ideas as to why this could be? I was actually already checking under the car to see if it loses fuel... We live in the suburbs and our trips can be considered a mix of urban and extra urban (they are admittedly on the short side and from a cold winter start; still, this doesn't justify the extremely low MPG). The car seems adequately powered for its weight and considering the small'ish engine and auto box.
