code 3, 41, 43 after turbo kit install on DC integra
hey guys...i just put my turbo kit on about a week or so ago and after having the car sit for a day or half a day when i start driving it the check engine light pops up and i get code 3 (MAP sensor), 41 (Primary oxygen sensor heater),and 43 (Fuel supply system) im running missing link fmu setup with stock injectors and walbro 255 intank pump. when i turn the car off and back on it goes right away and wont come up again until the next time the car sits for awhile. this seems like its a problem that a lot of people might have encountered in the past and i did try to search. any help is appreciated.
for code 41.... in your stock motor you have 2 O2 sensors. When you go turbo, you need to use the top one(not the one on the bottom of the cat but the one that was in your exhaust manifold). use the one from the manifold and screw it into the downpipe and make sure that you connect it to the correct plug. (not the plug that the bottom one was plugged into). as far as the injectors go it is very possible that youv maxed them out and need larger ones. any shop that works on hondas can tell you how to fix all these problems.
