I just finished swapping a sohc vtec in my 88 hatch and the motor relines at 3200 rpm. It doesnt rev pass that. I have codes 4, crank angle sensor and, 41, O2 sensor heater.

 

Did you search.

BTW Fix the Code 4 and it will Raise the Redline to were it Shuold be. I know this could have been found if you Search seeing as it has been covered many times befor.

d16z6 or d16y8 motor?

what ECU, what distributor? details details!!

 

I reconnected the two distributor wires today and used my friends chipped PO6 for a gsr and it ran fine, no codes, vtec kicking in at 4400. When I plugged my ecu which is a stock vx it ran shitty and did rev pass 3200, AGAIN. I figure that its the ecu. Would the problem go away if I have the ecu chipped?

 

By the way its a D15z1 block with d15b2 flat top pistons, d16z6 head, PO7 ecu and distributor.
