I have a low mileage one ton that I use to tow my camper. I have not put any miles on it lately except for starting it up and moving it in and out of the shop. It only has 24,000 total miles. The last couple of times I started it, it had an engine check light come on. Once it ran a little rough and I killed it and waited a minute and then restarted it. Then it ran fine. Now the dash information display says my exhaust is 80% full and needs to be regenerated. Can this be cured by a short road trip to get it hot or let it idle? I plan on checking into eliminating the system from the exhaust but have not looked into the best one yet. Any suggestions will help. Thanks.
