Hi , I have a honda civic ex 96 ,when is in idle and I turn on the a/c the rpm fluctuate, its go about 100 rpm up and down not that much, sometime went I accelerated to 2,000 rpm and let it go back to idle it work normal ,but most of the time that I'm driving and it goes to idle start fluctuate...

I have had the same issue with my car for the past few years. Basically, the RPM fluctuates erratically when it is warmed up. For example, if I have driving for a while (let’s say 30 minutes) and shut off my engine, then start it without giving it time to cool down, it begins to act up. Same thing...

I have a 91 honda civic 4 door sedan dx. I just replaced the rotor and distributor cap and now the car won't start. First I checked multiple times to be sure I had the firing order correct. I then read the thread written by CroCivic91 and checked my ECU codes. I got a 10 and 16. The 16 sounds...

Engine runs rough - a lack of power but not a hard miss - until engine warms up but car must sit for at least 18 hrs. 170,000 miles. Replaced plugs, cap rotor - no help. Distributor shaft has minor oil leak allowing oil to get inside of cap - maybe related.
