Car is bogging around 3.5k rpms when accelerating looking for insight and ideas I am having this problem with my 92 civic hatch back with the stock d15. When i take off it goes fine till about 3.5k to 4k rpms the engine cuts out and bogs. It makes a bumbum bumbum bumbum sound. If i let off alittle and push the gas pedal down it will power past it. This happens in ever gear at the same rpm if i am at half throttle. Also seems to happen after the engine is warmed up. I have flushed the fuel system , replaced filter, plugs , check the cap and it is alittle pitted but not to bad. I have tried adjusting the timing and still does the same thing. Any one have any ideas maybe the igniter or distributor ?
