I recently picked up a rather straight bodied 89 Civic HB w/ls swapped motor. i've since did a headgasket, timing belt, replaced dizzy, oxygen sensor, new alternator belt, replaced front forks since they appeared to have been from a EG (EJ) since they were to big for the tokicos!! I've had this car going on 3rd week now.

I am getting a code 1 and 4 when I have a pr4 in the car. Thats when I replaced the oxygen sensor (2 times) and replaced the dizzy once. Same results.

I have a ps9 that I put in to see if I still get code 1 and 4 knowing I'd get code 19. No codes beside 19.

WTF? Why wouldn't it show code 1 and 4.

I think my pr4 ecu is jacked so I am picking up another one today. The pr4 I have right now was chipped and the solder/desolder techniques look crappy.

Any ideas?

It was a DPFI converted to MPFI for the ls swap.

sorry to bump so soon but need to know ASAP. I am purchasing another ecu tonight if thats what you guys think!!!

 

bump for some help. on my way to throw money at another ecu. and hope it works

 

NVM figured it out.

Wasn't codes 1 and 4

It was code 14 (IACV). check my IACV sure enough its missing the plug to attach to it!!

I just spent over 120 bucks on unnecessary parts!!!
