Hello to all of my fellow Powerstrokers out there!
Luckily, I haven’t had many problems with my 99 7.3, but now I have an issue that renders my truck not drivable. So to the forums I go…
After the engine is warmed up, it starts romping…just like when you first start it in cold weather. Also, there is NO throttle response. It will run fine after it cools off 30 minutes or so. I had to use the truck yesterday and it worked out ok, because I never let it idle down. When I had to stop, I put it in neutral and kept the revs above 1500 rpms. So the problem appears to be related to loss of oil pressure to the injectors when the oil is warm and thinner. By keeping the oil pressure up with reving the engine, I’m maintaining enough oil pressure to fire the injectors. By the way, I let it idle all the way down after I made it home and once again, the engine started romping with no throttle response.
My new Auto Enginuity scanner should arrive today. This will be the beginning of my Powerstroke self education course and hopefully before too long, I’ll be able to talk the talk with you Powerstroke gear heads out there!
Any suggestions as where to begin looking with my scanner would be greatly appreciated and thanks in advance!
