I have a AMC 401 with a 260 cam, Mallory ignition and Howell TBI. I had the same TBI on a AMC 360 and it showed much the same symptoms.
The engine starts right up when cold and idles fine. When driving it is fine with the exception that it sometimes dies, without stuttering, after I hit it hard. It fires right up after it without problems.
When the engine has warmed up the idle is fluctuating all over the place, presently varying between 1250-1350 RPM's (in Park) but sometimes goes much lower and the engine dies. I could not leave the engine running for long without it dying on me.
I have changed the fuel filter (I have two, one before the fuel pump and one after) and checked the sock in the tank and cleaned the IAC.
Do you have any advise on what might be wrong'
Many thanks,
Palli
