    Hesitation at low rpm and fuel system goes to open loop

    Thanks again chaten. From what I can tell I have the exact problem you had. I'm going to pull the heads and take a look at everything, but I'm pretty sure it's the valves and/or pushrods. Here's the thread that I started before I found this one...

    Thanks for the quick reply! Did you also happen to have a tick that went away after ( i assume) replacing the valves and pushrods? I just removed my valve covers with the expectation of seeing evidence of a bad lifter and was shocked to see all 16 springs working fine.

    5.7L bogging down under load and low rpm

    Sorry I should have mentioned. They have about 5k on them at most. As soon as the weather clears up a bit here I'm going to start on that. I just need to gather parts and recommendations on what else I should fix while i'm elbow deep in'er. The only odd part if that is the culprit is that...

    5.7L bogging down under load and low rpm

    Hi everyone. 5.7L with 66RFE I have a 2017 2500 slt with about 200k km (125k miles). I've searched the forums but haven't quite found my situation. About a year ago, the truck started to struggle climbing hills ( my driveway is a 300' hill with turns covered in ice and snow) . I parked it...
