Civic Misfire at start WARM ENGINE ONLY
My car runs great...It starts up strong cold and runs great when driving.
HOWEVER, when it is warm and I go to start it it usually cranks 3-4 times (once/twice cold) and then idles at nearly 400 for a few seconds, then goes to 700... Once I start to move off (Manual) I will get misfire codes....Once i clear the codes (with scanner) and continue driving it is perfect.
I replaced all ignition parts, IACV, injectors...
could a bad o2 sensor cause this (what my buddy tells me)
PLEASE HELP ME!!!

Did you change the Distributer out as well? Whether you did or not, check the ignition timing. Also check the gapping on the spark plugs... Hell check for vacuum leaks too. All of that could cause what your experiencing.
