I have a 94 Saturn SC1 with a sohc engine. The engine cuts out at about 3000 rpm and loses all power. The fuel pressure is 30psi, and I have replaced the fuel pump and filter. The injector resistance is about 2 (within spec) and there are no codes. Any suggestions?

Your welcome kinda was looking like a plugged cat from the way you described your problem. Glad to hear you figured it out though.
