fuel injector?

Yeah your stock ones will be a orangish/brown color (19lbers). Is your MAF an aftermarket piece like a Pro-M or C&L or Granatelli? or stock (looking atleast)...post the part # and you can do a search on a search engine and you will usually get something to pop up about them. It will tell you what they came on...
 
i have a C&L and my injectors are baby blue. The C&L MAFS is brand new before i had the stock one on their i thought that was my problem but it just got worse. At least i know that my injectors and MAFS match. One less problem i have to deal with.
