Rough idle and gas smell - Express 3500
Posted: Mon Sep 16, 2024 6:38 pm
Hello everyone
I just got a Chevy Express 2003 3500 6.0. It was sitting for a long time and i got it in exhange for a job. I did an oil and fluid change, drained the old gas, installed new spark plugs. It turns on perfectly, and it drives smooth. The engine sounds really good too, it only has 125k miles. But when its on idle the engine misfires a little bit and there’s a smell of gas and a little bit of black smoke. The scanner says its the EGR Valve and i was going to replace it but to my surprise, the connector its not there. I looked everywhere, and i just can’t find it. My question is, are these sympthoms related to the EGR Valve or could it be something else? And if so, should i get a new harness or there’s another way to wire the connector?
