Why does it threaten to stall out at an idle, & sometimes will not accelerate? on 1995 Honda Accord

Sometimes the vehicle runs perfect. 50% of the time the Car hesitates, threatens to stall out at an idle, sometimes will not accelerate, makes popping sounds like small backfires when the tack hits near 3 while car is hesitating. Speedometer and odometer stopped working same time d4 light on instrument panel started flashing. Panel lights work intermittently. Was told I have a cracked engine block, bad speed sensor, and clogged air tube thingy which is supposedly only as wide as an ink pen.

Please post engine codes, should have check engine light on. Should at least have a P0700 code stored for the trans.('D' light flashing).Have Idle air control valve monitored for proper function. Cracked engine block? are you losing a lot of oil or coolant? Clogged air tube thingy--EGR? Need more specific info , does yours have V-TEC?
