I have a 94 Cadillac deville 4.9L ..when I drive it for about 20-30 mins it stalls out don't matter if I'm sitting at light or driving..it starts right back up..I was told my crankshaft sensors need to be replaced..then I was told that my car don't have crankshaft sensors and need to replace my distributor..can you tell me if my car has CSS and if so where the tell are they located...thank u

it's inside the dist, so get a rebuilt dist from a company with good guarantees like auto zone
