hello gang, this is a new post on stalling of my wifes 90 model after having some bad gas trouble,a new problem has arisen,when we decelerate it will about half the time, drop below 500rpm and stall. I have paid close attention to the tack when slowing down and some times it stalls when falling and at other time it catches itself and it jumps back to life but it sounds as if it stalled and relit( as if you just started the car.) the potentiometer is only a year old I wonder do they go out off adjustment.
