Hello everyone, hopefully somebody can shine a little light on this issue I’ve been having:
So I have a 2004 GMC Sierra 1500 RWD named Beulah and she is quite the beast… She’s got over 260,000 miles (given to me by my father after he used it as a work truck, so mostly highway mileage) and a few little kinks and issues. The one at hand today is some lugging/chugging of the engine usually after wet weather. I live near Lake Michigan and we just got dumped on by lake effect snow, but over this weekend it warmed up and we got quite a bit of rain. After this rain, I went to drive my truck and while it starts just fine and idles just fine, for about 10 or so minutes of initial driving, while at speeds anywhere from 0-30 miles an hour or so, Beulah seems to run a little rough. It almost sounds like she’s lugging a bit or something’s sticking in her engine. After about 10 minutes or so of driving it seems to fade away so my guess is its just some moisture getting into something and eventually evaporating from the heat of the engine. My questions are 1. Is this bad for my truck? 2. Is there a way to prevent this without spending a fortune? and 3. Any guess on how much longer this truck will last?
Much appreciated everyone,
