See the test below, It looks like once it reaches peak command, it does spike up and down. The last spike was at key off. This is just at 700 idle with the leakdown test. It's obvious it fails the leakdown test. However, on the other 3 ISX's i have not seen this when doing the leakdown test, it fluctuates, but not this much. Even the old rail leakdown tests, they stayed at 28500-29000 psi, not jumping up to 30k and down like this.



I want to hook up to it when it's loaded and pulling to see how it data logs then (but that won't be till Tuesday/Wednesday).
