Overflow Valve

My Ď98 12 valve seems to lack power at 2000 rpm and up.I havenít checked my fuel pressures yet but I did pull the OFV and checked the spring. It was still intact and measured exactly 0.50Ē in length. Could it still be a bad OFV or did that rule it out?

I donít know the answer for sure but did add the pen-spring-trick to mine recently and performance improved everywhere. I put the spring in and cut it the same length as the stock springís length.
