Hey ht
My car has been giving me a code 9 for awhile now(d16y7) (obd0 pm6) , it's ran great except it would bog every now and then. I moved some wires around and when I went to start it the code 9 was gone but then it gave me a code 4, throwing me in limp mode.
. I checked my wires from the distributor to the ecu to make sure they were all intact, which they were.
Next I picked up another ecu and it still gave me a code 4. So I went to the pick and pull and snagged a dizzy of a d15b2 I had to chop the wires because I didn't have a conversion harness, nor did I want to buy one, I matched the wires to my knowledge correctly, I'll upload a pic tomorrow and see if yall can tell if I wired it up right.
Are there any other things I need to check over to get rid of this code.
TIA

 

Here's a pic of the wiring on the distributor. I believe this is the right way, I just wanted to know if I connect the smaller white wire or not,
also my car backfires like crazy, when I let off the gas it sounds like popcorn I'm not sure if this would be related to being in limp mode still.

 

a D15B2 DPFI distributor won't work with a PM6 MPFI ECU - if you are MPFI, you need the distributor from MPFI Civic Si/EX or CRX Si/HF - if you are running it with the DPFI, you need a DPFI ECU
