nothing wrong with needing advice, but you should have a manual for your car. it will save you money. sparkplugs or injectors? it's very easy to replace either of them on your engine. do not pay a mechanic when it will only take less then 15 minutes to replace either the injectors or the plugs. don't know why you would have to replace injectors, but if you are replacing them to upgrade your fuel system, go with the late model prelude injectors. i believe they are 280cc and they drop right in and you can find them on the partstrader for cheap. also, get some seal grease so you don't damage the orings on the injectors when sliding them in.
