Before you post ...

1. Register: If you decide to sign up for an account, DO NOT use your email address as a display name. This increases the amount of spam and scam email you get, and puts you at more risk of account hacking.
2. Read the rules. We expect everyone to know them, and offenders will be removed without warning.
3. Read the FAQ: We have a list of the most commonly asked questions in the forum. Check the list before you ask.
4. Search: Use the search box in the top right corner and search keywords about your problem. There is a very good chance that somebody has already asked the same question, and the solution has been posted. Our generous members have volunteered their precious free time to write thoughtful answers, so don't let it go to waste.
5. Title: Write a clear, concise descriptive title. "Help me" or "I have a problem" are bad titles. You are more likely to get help with a title such as "How do I fix a vibrating Corolla motor". Do not use ALL CAPITAL LETTERS.
6. Vehicle details: Please, please... Always provide your vehicle info. Even if you think it doesn't matter. We can't help you properly if we don't have all the details. At minimum: Year, Make, Model, Odometer reading, Transmission. Engine type, related aftermarket accessories etc. and the more additional information about the problem that can provide, the better answer you will get. For example: if you need help identifying a sound, try to find out where it's coming from. Or if you have an electrical problem, then knowing the battery voltage is crucial.
7. Troubleshooting details: If you are asking about a problem that you have already started working on, then please list all the troubleshooting you have already done. There's nothing more annoying than taking the time to type out troubleshooting steps for someone, and they tell you they already tried it. It just wastes everybody's time and leads to more frustration. Tell us everything.
8. Photos/video: Troubleshooting over the internet without the vehicle in front of you is difficult enough. When you start describing "that metal thing, is hitting that rubber part , which isn't pointing in the right direction", we have no idea what you're talking about. Just take SEVERAL good pictures with your smart phone. Upload them to a image sharing site (such as postimages.org) and post the image links in your question. Better yet, if it's something that moves, or a sound that you hear, then upload a video to Youtube.com and post the link.  It's really easy with the app. This will help immensely with troubleshooting.
9. Be polite: This really goes a long way when asking for help. People here volunteer their free time to help you because they enjoy it. They could be doing something else. Sometimes you may not get a satisfactory answer.  Misunderstandings happen. Restate or clarify your question, or just thank them and solicit additional answers. If you are rude, we will probably ignore you.
10. Multiple questions: Please post each question separately. You will get less answers if you lump them together.
11. Answering questions: You think you know the answer to somebody's question and you want to help them out. That's great. We really appreciate it. Please enter your answer at the bottom of the page in the box labelled "Your Answer". Do no use "Add a comment" for answers. Thanks!
