Have a very weird problem. Have a 97 1500 with a 5.9L motor. Given me 130k with absolutely no problems. Truck looks and runs like new so I'd like to keep it. But I've developed a strange problem. Heard loud bangs from the engine at an inconsistent rate. Maybe 4 or 5 per minute then nothing for 30 seconds then 5 or 6 times in a row then silence for a while then bang bang again. while checking it out I saw the tension idler was the culprit. changed the idler and belt and checked all the pulleys and they were fine. Started it up and there she goes again. almost like something is trying to stop the engine. Rechecked all the pulleys and all and everything seems OK. Anyone seen this. Like to do my own wrenching but don't know where to start. Find me the problem and the beer is on me.
