Mike -
Just do it!
AFAIK - You have two issues. A leaky fuel rail, and a throttle cable that sticks near idle.
Go to Ace right now with your O Rings. You can have that problem fixed by noon.
The throttle cable will take a little longer. If it's not unsafe, then take your car out.
"'Better' is the enemy of 'Good Enough'".
Look at BDUD. A catastrophic engine failure about 4 weeks ago, I expect to see him back on the road about two weeks from now.
And BDUD only has one thread, with a series of posts providing his diagnosis, his path forward and his results.
Good Luck -
