From the looks of it, the p1259 code could be telling you that this is your idling problem, if all bolts arent tight or the wiring is messed up.
Honda Accord VTEC Solenoid Gaskets Replacement - YouTube this is a great video on how to replace the gasket on the Vtec solenoid gasket, its for the fifth generation Accord, but the work was easier on my seventh generation Accord because my solenoid was on the back of my engine without stuff being in the way. I would check everything you can about this part- grounds, wires, pressure switch, solenoid, gasket, oil leaks? anything revolving around this and it may fix your problem!
Another detail on this problem is from this website.https://www.hondaaccordforum.com/for...code-52497/--- please let me know how the problem worked out for you after you fix it! I am very curious.
By the way, changing the gasket on my Vtec solenoid took roughly 45 minutes because it was difficult to reach and I was gentle not to break the bolts! It cost me less than $20 and the fix cleared my low oil pressure code. Just do the research before you dive in,
Good Luck!

Well since I've owned the car I've done regular oil changes only 1 time i went over and was about 1000 miles over doing the oil change. One time I used the wrong weight of oil I read the label spot but not the actual bottle and after the oil changed realized what i had did. i think my motor is 5w 30 and i used i think 10w 30 id have to double check that. I wasn't sure if it was throwing the code bc of that or if it really is something else. I'm hoping to dive into working on it this weekend if my check actually gets deposited (work BS) I'll definitely update when i check out some things.

Similar situation I just went through cost me $700.00 to figure out the bolt on the throttle body was loose and grounding the car out after a minute or two of running until one day it wouldn't crank at all. Check all your work!
