I have Bought a Cadillac Seville 1994 SLS and since then I have had problem's with the engine run meaning thatthe engine while running will all of a sudden start pulsating and will shut off while sitting at a stop light or starting to accelerate so I was told that it maybe the crankshaft and the camshaft sensor's at least that is what the Diagnostic tells me just wanted to make sure and see if other people have had the same problem as I do THANKS.
