Alright I have a 91 honda crx dx. I just finished installing a d16z6 sohc vtec. I switched everything over to mpfi and am running a p28 ecu. We were having trouble getting all four injectors to work but we finally figured it out. Of course it was something simple and it was the 15 amp fuse for the ecu. There was no power going to the ecu so we replaced it. and now everything works. When i went to take it for the first drive it would be very slow getting up and when it hits 3k rpm it bogs and sputters and wont let me past 3k. I checked for codes being thrown and it showed me a 4, 14, and a 41. I started with the simplest and wired the o2 sensor up right and then it did not flash anymore codes and still does the same bogging. The Check engine light stays on but theres no more codes. I am just wondering what could be the problem with the bogging and sputtering? Any help would be greatly appreciated, thanks alot

 

You did a full engine swap??? (Transmission, block, head, IM, EM, Wiring harness, ECU???)

 

yea i did a full swap, everything is converted. But i figured it out, ended up i had to reset the ecu. Ha of course something as stupid as that
