FiRe_OpTiKz© Posted October 30, 2006 Share Posted October 30, 2006 no it's called back pressure when your car revs right around 3. - 5 grand your backprssure builds and thats what causes your motor to backfire or Misfire it's not a bad thing. my hatch does it and it's built i just need a turbo because im running so low of a compression that it does have the back pressure power to keep the air flowing correctly Link to comment Share on other sites More sharing options...

Kegger Posted October 31, 2006 Share Posted October 31, 2006 It's prolly cuz you're running a little rich or your ignition timing is advanced just a tad bit too far. Link to comment Share on other sites More sharing options...

cranny Posted October 31, 2006 Share Posted October 31, 2006 its backfiring most likely , cause you have too low of compression to run without boost. Link to comment Share on other sites More sharing options...

GElite Posted November 1, 2006 Share Posted November 1, 2006 My 92 Civic Hatch backfires a little bit between each shift. It has a B18B1 LS VTEC conversion in it with a custome exaust and no catalitic converter. Its running a little rich and the rings are about shot. All perfect condtions for un-burned fuel to be in the exaust but any one of those conditions by its self could cause it. There are so many diffrent things that could cause it. Your thermo sensor could be bad which causes the car to run rich n order to make it run hotter. When the sensor goes bad it thinks that the car is running cooler than it actually is.
