Good afternoon i recently purchased a 2000 accord ex 4dr 4cyl 5 speed, it currently has 207k on it. When i purchased it had the 1166 and 1167 and she was told everything was normal car was running fine. Very short distance i found that the car is idleing @700 rpm and you can feel a miss or feels like a miss. IMO i have to give more throttle than i want to take off so it does not stall out while driving the unit runns semi smooth as long as the RPMs stay above 2200 anything below itll start to show the miss again 5th gear it needs to deff stay above 2200. I have done cap rotor plugs and wires 3 plugs were ehh 1 showed leanish and the cap was terrible shaped. the check engine flashes when RPM is down orher wise its steady and i find that if there is an electrical load the light starts flashing earlier and the miss/studder starts earlier. I realize i need to change the first O2 inline but keep finding different answers on which to get one site shows 2349014 and next 2349025, but is there a possibility with such a low idle the alt is just not enough for the car currently to keep up as well. Is there any where i should be starting or looking directly thank you for any assistance avail
