I have a 1994 ford mustang cobra. A couple of months ago the rpms started surging and the car cuts out when at idle acceleration and at crusing speed. This is my first car and i can not find out what is wrong with it and i dont have a check engine light on and cant have a test done on it cause i dont have a cadillac converter instead i have a off road h-pipe. I have replaced the fuel filter, spark plugs and wires, mass air flow sensor, O2 sensor, TPS sensor. And i also checked the fuel injectors and fuel pressure and are all working fine. And also all the pressur is normal in the engine. I dont know what to do and my brother is in iraq and cant help me. So please if someone has any advice that can help!
Thank you for your help and your time,
Spencer
