Only for questions that don't better fit in a tech forum
The Problem Diagnosis forum is only to be used for questions that don't better fit in another more specific forum. For example, if your car is stalling and you don't know what the problem is, post your question here. The problem could be fuel, ECU, etc. However, if you know that your problem is brake-specific, drivetrain-specific, turbo system-specific, ECU-specific, etc, it should be posted in the appropriate forum. This forum is here to help people narrow down and identify a general problem that they otherwise wouldn't know the source of. If your clutch is making a strange sound, then post in the Power Mods forum, not here.
