My H22 is acting up and neither I or some friends could figure it out. I removed half of my stock intake beneath the fender and a vacuum line connected to butterfly valve on the first part of the intake tube (explained more in a previous post). Everything was running fine for maybe a week but yesterday the car seemed like it just didn't want to accelerate. There was no throttle response and the worst part was when the car would engage VTEC, it was much louder and would actually accelerate slower and didn't even want to rev to redline. I think that the problem must be with something in the air/fuel system or caused by that vacuum line that i plugged and left under the hood. Any Ideas?
