I've got a 95 Olds Silhouette with 3800 engine. Recently it's lost power and a diagnostics place says the knock sensor (Electronic Spark Control) is "hearing" a very slight internal knock at 2000 rpm, misinterpreting it as spark knock, and retarding the timing 15 degrees ..with significant loss of power. They said nothing can be done and mentioned maybe "a replacement engine". They've got to be kidding. Some computer system is accidentally retarding my ignition timing and I'm supposed to replace the engine ..or scrap the car out?? Anyone have a less drastic solution? Thanks.
