inspect and possible replace EGR.

vtec will not engage with those codes running.

 

VTEC doesn't care about 4 wire O2 sensors, or EGR valves. Coolant temp, RPM, VSS, TPS, VTS, VTP, MAP is what the VTEC code looks for.

Sounds like the wrong ECU to me.

 

i had the p28 in it and it was kickin a rev limiter in at 6000 so i switched it with my buddies and it took the limiter away but the v tec still didnt work so i have a p06 in it right now obveously vtec isnt there so would it be better to get a good p28 or should i get an rpm activated switch from jcwhitney and run it that way

 

did u remove the screw from the block?

 

How about you back up a good bit and tell us more details about your car, and a timeline of what's been done recently + when exactly you started having problems.

 

im having kind of the wrong problem as well v-tec is not kicking in.did u solve wath was wrong with it?.
