On the P1281, could be possible that the t'stat is stuck open.
On the P0442, check the lines at the evap canister, the lines under the hood
(near the green test port), and the gas cap o-ring. Those the the most
common spots where you'll get the 442 code. If you can, try to borrow a
scanner and find out how many key-cycles and/or minutes the code has been
present. This will tell you how long and roughly a time frame on when it
first happened. BTW: Locking gas caps are also known for throwing this
code as they don't always seal properly.
Last place to look would be at the NVLD (Natural Vacuum Leak Detection pump)
next to the EVAP canister. There's an o-ring that does leak after a
while...but you'd probably also have a P0440 code.

Hey, DML
Help! Tried to get the DAKSY inspected today & the local guy won't do it
with the MIL.
I've got a week on the 04 sticker...
According to the Bible:
P1281 - Engine is cold too long ... Engine coolant temperature remains below
normal
operating temperatures
during vehicle travel(T-stat)
What do I do? Remove the Robt Shaw 180 deg & return to the stock195?
I've got plenty of heat, so I don't think the 180 is stuck in the open
position...
Am I missing something, here?
P0442 - Evap Leak Monitor Medium Leak Detected...I know - I gotta blow smoke
thru the system in order to find the leak...I can't find a smoke machine
anywhere around here....If I could, I'd still hafta figger out the fittings
req'd to connect to the Evap sys...
I'd rather not go to a dealer, but looks like I have no choice...It'd be
different if I could get into a heated garage & play, but THAT's not gonna
happen til I get done with the A-frame...
Help!?!?!?!
