I just noticed that along with my VTEC-E swap into my '95 Civic CX they put a cover over the EGR valve, (blanked it off), and there is no box with the solenoid and vacuum control valve, does it matter? I've also got a P08 ECU, non-stock exhaust manifold (4 into 2), with 4 wire 02 sensor. Power seems good, idle is 750 rpm (a little fluctuation), but mpg is terrible, definitely worse than the original 16 valve Canadian CX engine. I just got a P07 ECU and I'm going to get a 5 wire 02 sensor, hopefully with the stock manifold, does the EGR valve matter?
