We've gone over this a tremendous amount of times here on PFF. Especially with searches.
The biggest issue is thread titles. Don't start your tech thread title with "OMG!11! sUPer DuPEr HXZORS OMG prOBLeM w/ MAI fiero YO!", or "good God Almighty help me please!!!1111one!", or similar. The first thing that is seen in a search query is the thread title, so an effectively titled thread can make subsequent searching easier.
The other REALLY BIG thing is the VERY first post of a tech thread should include everything relevant about your Fiero. Not everyone here knows what every single person drives, and even though some may not think it I would surmise that about 90% of tech questions asked are very specific to a particular year Fiero and trim level. The year, trim level (GT, SE, etc), relevant options (like maybe transmission option), etc, should always be put in the very first post; really it should be the first sentence BEFORE you even state the problem.
I don't claim to know everything too, not about cars in general or even Fieros, but man it can be really difficult to help in tech sometimes with how threads play out.
