Step 1: The Air BoxShow All ItemsTest Point 24: Alternator, Regulator Misfiring of the engine could be caused by the peak voltage of the alternator. Take drive belt off of the alternator. Check alternator and regulator if the disturbances have been eliminated. Test Point 25: Leads K and L Connections for diagnosing between the DME control unit and fasters are made with both leads K and L Check the folIowing points when diagnosing is not possible. 1. Power flow test (see wiring diagram) Lead L: Pin 7 (19-pin diagnostics socket) - Pin 13 (DME plug) Lead K: Pin 8 (19-pin diagnostics socket) - Pin 55 (DME plug) 2. Ground short test (see wiring diagram) Lead L: Voltage on Pin 7 (19-pin diagnostics socket) must be > 8 V with the ignition turned on. Lead K: Voltage on pin 8 (19-pin diagnostics socket) must be > 8 V with the ignition turned on. Possible Causes of Fault: Ground short or break in wiring or plug connections. Faulty control unit, which is connected on these leads (could be any diagnosable control unit; does not always have to be the DME control unit).

Checking: Pull off plugs on diagnosable control units one after the other until there is> 8 V. Replace fault-eausing control unit. Power supply lacking on diagnostics socket. Ground supply lacking on diagnostics socket. Information for idle speed and idle speed CO test: 944 S engines have adaptive idle speed volumetric efficiency regulation since 1987 modeIs. This means that the idle speed of all versions does not have to be adjusted. The system of cars with adaptive idle speed volumetric efficiency regulation should be adapted each time the DME control unit had been disconnected on permanent positive or after each inspection. Idle speed control value for engine at operating temperature: 840 +- 40 rpm b) Idle speed CO of cars without catalytic converter CO level is still adjusted on the CO adjusting screw in the air flow sensor. Engine at operating temperature. Engine and ignition in perfect running condition. All electric consumers switched off.

However, not everyone agrees on what preventive maintenance is, what you should do, and when you should do it. Let's clear that up, and give you some tips that'll apply to any vehicle.

Anyone who's ever worked on cars or spent a ton of money getting their car repaired will tell you: Don't ignore preventive maintenance. The basics, like changing your oil, checking your tire pressure, and getting scheduled inspections and work done are like getting regular checkups at the doctor. They keep you healthy and give you—and the experts—a chance to catch anything serious before it becomes a major problem. With your car, that can save you thousands. Pay attention to your owner's manual. Regardless of the vehicle you drive, your regular maintenance schedule is inside it, and you'll never fall for old car myths like, "You should change your oil every 3,000 miles," (unless of course, your manual says you should, and odds are it doesn't). You will, however, discover how often your manufacturer really does suggest you change your oil (it can vary widely by vehicle), your filters, any drive or timing belts in your vehicle, and more. You'll even find out whether you're putting the right gas in your vehicle or whether you're using the right kind of oil in the first place.

Seriously—you wouldn't fire up a complicated piece of technology or a massive new home appliance without checking the manual to make sure you know what you're doing. Most car lovers already know how important this is, but it's still important even for people don't consider themselves interested in how their car works. If you're using the wrong oil, for example, or filling a car that calls for higher octane fuel with the lowest octane stuff you can buy, you may run the risk of voiding your warranty, and worse, causing damage that'll cost more to fix than you'd save by using the cheap stuff. When we covered the ways you can save serious money on car repair, more than a few people pointed out that preventive maintenance is probably one of the biggest ways you can save money—not actively, but in the long term. Spending a little money now on these basics will save you from more costly repairs later on: These are just a few things that every vehicle needs, and almost all of them are things you can do yourself.

We can't stress enough the importance of checking your owner's manual for anything we may have overlooked here, or anything specific to your vehicle. If you don't have your manual, you can find it pretty easily online. Check with your manufacturer first—they may even have a PDF copy on their website. If not, Edmunds has a list of online manuals here organized by manufacturer (US only). Our friends at Jalopnik turned us on to Just Give Me The Damn Manual, which is a real windfall. If you still can't find it, you can probably order a copy from Helm, Inc, or pick up a Haynes Manual which, although they're aimed at the DIY enthusiast, will tell you everything you need to know. Remember, preventive maintenance can save you a ton. It's not just something mechanics and car people tell you to do to spend money. Keeping tabs on the work you have done to your car can be a pain. I like to keep my receipts in the glove compartment so I can look through them when I'm in the car if I need to, but that's no real filing system—you could do just as well scanning your maintenance receipts and putting them into Dropbox or Evernote, or whatever other note-taking tool you prefer.
