FUEL PRESSURE!!
I have 680cc and aem fuel rail and aem fuel pressure regulator.. I noticed my idle was rough I check the fuel pressure gauge and it was shaky..I tapped on it with a wrench and it held steady and idle was better..I opened up the fpr and the diaphram is like new.. Its the newer design..Maybe the spring is stickin? help!
