comment Why can some cars go through water while others can't?
Don't forget about electronics, even just the distributor. Water (assuming it isn't pure H2O) is very good about letting electrons go places they shouldn't, usually to bad results. Now, if your car is an old diesel with mechanical fuel pumps, then you don't have much to worry about.

comment EVAP System or faulty CEL?
If you have a laptop, Android tablet/phone, or even an iThingy, you might want to pick up a USB (for the laptop) or Bluetooth ODBII adapter. The cheap ones are < $20 on Amazon. There are various software packages to use the adapters for Windows, Mac, Android, and iOS.

comment 2008 Pontiac Grand Prix Fails to Start and Electronics Go Awry
Some more to help diagnose the problem: If you turn on the interior lights and the headlights, do the lights dim when you try to start the car or do they stay the same?

comment How do I mix up my own windshield washing liquid for low temperatures?
I've been using the RainX washerfluid for a few years now. It hasn't frozen yet for me, even at 5F (-15C). As a plus, it also keeps a nice coat of RainX on the windshield.

comment 2006 Audi A4 2.0T, No passing power
It sounds like you may have a problem with the Turbo. Does the car have a boost guage? If so, does it show boost under full throttle? Also, did this start suddenly or has this been getting worse over time?

comment What should I look at when my brakes are soft?
@MikeWills Slamming on the brakes in not the same a properly bedding (burnishing) them. [Slamming on the brakes may cause glazing of the pads which will make matters worse.] A crucial part of the bedding process is to get the brakes hot enough to make sure the resins present in the pads are baked out of the pad. Not doing so may result in "green fade" (see about 1/2 way down on the StopTech Page on Bedding Brakes) .

comment Brightening dim headlights
The light pattern on the 940 Volvos is the biggest problem I have found. Unless the lenses are changed, having the extra light of HID doesn't really help get the light were it is needed.

comment Engine never warms up (actually: it cools down) at highway speeds
@Robbie Thermostats usually die because of old age, so there shouldn't be anything else to look at.
