ISX

Mentioned this a few weeks ago. Seemed to resolve itself. Basically it started having an issue where it was like you took your foot off the pedal then back on it as fast as you can. Like it was dieing for a sec. I changed the CPS and it seemed fine for a few weeks. Well now its much worse. None of the gauges seem to turn off when it does it. I did use a new OEM CPS..

It only does it at around 5-10% throttle (guessing). Doesn't do it if you are getting on it at all. Idles fine never dies.

It does have 272k miles on it with almost no maintenance done in the last 100k besides basic changes.

Any ideas?

I had a similar symptom when my TPS went bad.
