Pete 587 isx15 acceleration issue

Anyone who owns one of these engines should have a laptop with the insite program on it and an inline adapter.These tools are readily available for about $300 online.

If you had insite you could monitor throttle position and see if there is a discrepancy that points towards a bad throttle position sensor. You could also look at engine state monitor to see what's controlling the throttle when this happens.

There are countless other things you can do with insite to help diagnose and maintain a cummins engine. Without out it we just sit here guessing and wasting time/money.

You could connect with insite and then go about your day as normal and then when it acts up you can take a look at the data your monitoring.

Has the check engine light come on at all lately?
