low icp v and icp press

My icp v is reading .8-.9 at idle. Icp psi reads 570-600 occasionaly dropping to 530-540. Truck idles poorly, sounds like its misfiring or injectors are not firing properly. Only does this in park, runs fine in drive. Brand new icp sensor. Ficm voltage is reading 50v io Edge cts (58v ficm).

Sounds like a small HPO leak somewhere. Mine will idle at .9v but holds steady at 570/580. If your dropping to 530 and it's stumbles you have an issue.

Mine when at operating temp fluctuates 0.7-0.9 when idling in drive... No idling issues. Sounds like an injector issue? get the IDS on it so there is no guessing involved

Yes you did and I've already made the phone call. He said its normal and I need new tuning and ficm tuning. Not the route I want to go. Just want to make sure 100% it can't be something else.

Am I the only guy who had had 3 sets of warren injectors in 6 months! This is riduculious. Don't want to mask this problem with computer tuning.

Very frusterating not being able to let my truck idle in the winter because its shaking and sounds like its breaking down. Everyone asks whats wrong with my truck too, ughhhh

That is not normal. I have his injectors and mine do NOT idle like that at all. They idle like stock sticks do. Try one thing. Have a tune writer write you a file with the idle kicked up to around 900 Rpms and see what happens. Tell them that is all you want revised in one of your current tunes. That will answer the question on my theory.
