• To ALL forum users - As of late I have been getting quite a few private messages with questions about build ups here on the forum, or tech questions about your personal project. While I appreciate the interest, sending me a private message about these topics distracts from, and undermines the purpose of having a forum here. During the day I wear many hats as a small business owner-operator and I work tirelessly to provide the absolute best service possible to you, our valued customer. When I created this forum I rounded up some of the best minds I knew so that any tech question you might have could be asked and answered by either myself or one of my highly experienced moderators, this way the next time this same question is asked the answer can be easily found and utilized by the next IH enthusiast having the same question. This allows me the freedom to run the day to day operations of the business and minimize the impact to shipments and shop activities that these distractions can cause. It is of the up most importance for me to complete the daily tasks in order to best take care of you our customer, all the while providing you a forum to get the level advice and input you have come to expect and deserve from the premier IH shop in the country.

    So with that I ask that anyone with a question about one of our build ups or a general tech question to please use the forum as it was intended. I am absolutely available by telephone to answer your questions as well but at times may direct you back to our website to better field your question or questions. Most other private messages I will be glad to answer for you.

    Thank you for your understanding.

This is an odd one, the Scout has been parked for a while, figured I had bad gas. New gas and fuel filter. Runs fine at idle.
Fuel pressure at 12 psi which is right were I set it many years ago.

When driving, it surges. The injectors are not dumping in fuel. Pressure looks good when driving
I can rev the engine when parked and its fine. One time it started to run like it did when driving and I can see the injectors not spraying fuel. I ran a can of injector cleaner through at idle just in case. No difference and the spray pattern looks fine

I logged data, but it been years since since I really looked at the data. This really short as the problem happen real fast.
The Scout feels like I'm stepping on the gas and taking my foot off, when in fact I'm not

Realized I did not get the blm data, so took it out for a quick run.

But its running way better, no surging.

Will need to test it out more on sat. Attached are the data files
