I have a 93 Integra with a 1.8 LS. I am getting a code 43. this is a fuel delivery issue. The car seems to run fine under throttle and the only hiccup seems to be at idle. Every once in a while has a slow idle accompanied by a slight misfire. I have put new injectors and computer in the car but that didnt seem to fix the problem. Any input would be greatly appreciated.

 

Check your battery grounds, and check for a vacuum leak. Ofcourse if you havent changed your fuel filter, now is a good time.

 

I have checked the vacum lines and i havnt ran across any bad grounds that i have seen i am gonna replace fuel filter but i dont think thats it cause it dont act like its clogged when you blow air through it i was just wandering if any one else has seen this and what they did to correct it

 

O2 sensor fixed it thanks for any help or input that anyone gave.
