hello my 2000 Honda Insight M/T backfires from the intake under load and slow speeds only. It will backfire when if I stab the throttle real quick or whenever the engine is at lower rpm's example: going around a corner in 2nd gear and accelerating. I am going to change the spark plugs the ones in there now are very dark almost looks like the engine is running rich. Other than that it runs fine. All theories and explanations welcome. Thanks,

If you have a compression gauge, you might want to check the compression while changing the plugs. You may have a intake valve clearance that has tightened up or even a burnt valve.
