On April 26th I posted the problem I was having with my Check Engine Light coming on while traveling. It even got worse. Sometimes it took 30 minutes for it to go out when first starting up in the morning. When it would go out, I could drive all day without it coming on. After a few furstration days on the road , I stopped at Transwest RV and Truck Center in Frederick, CO. They are listed as an Oasis Frieghtliner Service Center. Arrived on Tuesday. Made an appointment for Wednesday morning, In by 8am out at 12:30 pm. After doing the compter code check, the tech deterimes the Injection Actuation Pressure Control Sensor is bad and is replaced. 3 days and over 800 miles latter, All is Well......

OP here.....I did change the fuel filter about a month and at least 1000 miles before this started. I have changed the fuel filter on the unit at least once a year, maybe more. Always careful to fill from the outside holes till full. If by change I got air into the fuel system, will it self bleed? Thanks for the replies, Jim

2004 Winnebago Journey with Cat 3126. Long story. Started about 2 months ago coming from California to Mesa, AZ. About an half hour into my journey traveling with the cruise set at 65mph, the check engine comes on and I loose power. Stays on for just seconds and goes out and resume speed. All gauges check OK. About an half hour later, same thing happens. . Get to our Campground and make an appointment at the Frightliner Shop in Chandler, AZ. Arrive early and start work on it. Just observing, looks like that have it hook up to the computer for at least a half hour. Shop Foreman comes by and states they want to road test. Gone for at least a half hour. Foreman comes back and tells me that the Tech cannot find any problems. Give me a bill and sends me on my way. All is well for 100 mile trip to our next stop. Now a month latter, upon leaving the campground in Cottonwood, AZ the engine light comes on and goes into the limp mode. I get off the highway, park and turn off the engine. Wait a few minutes and try and start. Will not start. Wait some more. Will not start. I have it towed to a shop. The tech hooks it up to his computer and reads the codes. He then want me to try and start the Cat. It starts....He scratches his head, looks dumb founded and states that he does not know what to do. Gives me a bill and sends me down the road. I have now relocated twice with no Check Engine light coming on. Nest trip is going to be remote. Northern AZ and NM. Almost afraid to get on the road. Anyone have any similar experience, or any Check Engine light problems?
