Re: 93 Blazer CPI Rough Idle...
Im picking up alot of spark knock on my engine, I run a data logger, and it counts the knocks. It will get very very very high at times... I never felt my idle was as it should be, but commonly wrote that off with the mods I did to it. I think my shitty Advance Auto spider died again... This will be the third replacment of their defective spiders, along with the countless defective heater cores, sensors, and other random moving parts. I dont think their parts are made to work for months at a time, kinda some sorta drive it one day a year parts or they might break from excessive use. Any who, I have no idea where the knock is comming from... I also have no idea with my spark advance runs so high... and jumps so much... I dont kno why that whole god damn system is even on my blazer... I hate it, i really dont see the need to advance and retard timing based on the judgment of a shitty quality sensor that senses noise in about the noisiest place ever. Damn shits just stupid.
