Default cruise holds 50% time

04 grand cherokee 4.7L HO cruise control?

If it holds at all on flat road, I slow 5mph below setting about 50% of the time; and will not accelerate up an even small hill. where do I start looking?

Welcome to CF. I'd start off by checking for any cracked/loose vacuum lines and verify the vacuum canister is hooked up & not damaged.
Here's the '04 WJ's vacuum canister.
