This is my first post. I have a 73 Mustang 351 Cleveland. It has a new refurbished 351 Cleveland, new 4BBL Edelbrock carb, new electronic distributor and coil, new gas tank and sending unit, 2 new gas filters. The timing has been set where it needs to be according to the timing light, and I have replaced the vacuum lines. The only way to keep my car from stalling when I take it out of park is to idle it twice as high as it should be. When the idle is set normally, it stalls out the second I put it in reverse or drive. Any advice as to what might be wrong with it will be greatly appreciated!! :shrug:
