Engine dies when decelerating AND making a right hand turn (at slow speed); as when approaching an intersection. Engine dies if making a right had turn from a dead stop; while very, very slowly accelerating in the right hand turn or turning right at a very slow speed. Engine can immediately be restarted in all of the above cases. Just hope some fool isn't following too close.

A right hand turn can be accomplished without the engine dying IF: I accelerate sharply from a dead stop while making the right hand turn.

They are NO problems when driving straight or making left hand turns at any slow or fast speeds; whether accelerating, decelerating or at a steady speed.

I have replaced the plug wires & coil wire and visual checked all wiring in the engine compartment I could visually see. I'm thinking it might be an electrical short somewhere I can't easily see or a fuel pump / gas filter problem?
