Dieseling and Slight Backfire - 250I6
Hi Everyone,
Ever since I picked up my truck, I've noticed that it has been dieseling slightly (Idling a bit after ignition is turned off, 2-3 seconds). Additionally, when I am gearing down, I thought I was hearing a slight backfire in the engine compartment. So, after running some sea foam through the oil/fuel and changing the oil and filter, the problem still persists. Today, I thought I would check the vacuum on the carburetor as perhaps the air/fuel mixture was slightly off and perhaps the truck was running lean. After getting under the hood, I noticed some black exhaust on my block. I'll attach a picture, it appears as though my exhaust manifold is either cracked or not sealed properly. Anyhow, going to look at replacing the manifold. Would it be fare to assume the dieseling/backfire is coming from this? Thanks for your input, Mike Last edited by Mike-P; 10-12-2016 at 07:20 PM. |
