i have an obd1 h22a in my hatch. lately i was messing around with my buddy and his altezza. it seems that half the time vtec will hit at 5500 and continue to rev to the 7400 redline. but the other half it wont kick and i hit fuel cut at around 6900. only CEL is egr and it is hit or miss on wether it will hit or not

 

probably a bad dizzy
