Curious if a few days of warm weather running 'winter fuel' can aggravate a slight dieseling issue I have on my B2300.
Went to Southern Maine on X-mas day where temps were quite balmy and my 2300 dieseled badly under slight load on the highway (2K-2.5K rpm)
It was bad enough for me to pull off and top off with 91, which didn't help much. Vehicle seems to be mildly prone to this; I usually tailor my driving style to avoid it, but this day it was pretty bad. I read there is a knock sensor under the manifold, apparently for nothing?
Looking for suggestion on what might be causing this and if it can be resolved; I'm figuring more volatile winter fuel on a warm day detonates more readily.
100K miles; 2.3L duratech; usually 87 or 89 Valero fuel.
Thanks.
