1998 Honda accord ex 3.l vtech 6 cyl

250000 miles 

my d4 light blinks on the dash ? 

I bought the thing for dirt cheap had a bounce of codes cleared drove around some came back I’ve been knocking them out one by one…. Long story short I’m down to one code left and the light is still blinking. 
the code is p1705

auto zone says it’s the main relay I replaced that too the code came back after clearing n don’t know what to do.

also the car does a little jerk when I come out of park almost like a bad shift but it’s not and the car shakes. My transmission fluid is a little high maybe half an inch over could that cause blinking light? But I feel like it wouldnt cause the code. So I feel the the p1705 has something to do with it 

also, when I come to a stop at a light and I’m still in drive, I don’t get a jerk when I proceed to accelerate. It’s only when I’m pulling it from park into reverse or drive..  it’s an automatic btw

please help your the man
