I've been working on my moms car for a long time now, she bought it used from the dealer and they got her good. Car supposedly had 63k on it when she got it but the shape it was in looked more like 250k. I'll cut to the chase, the car has a random miss in it. it will miss then try to stall out, it used to actually die before I messed with it. Its throwing a code (at random) for high fuel pressure crap, which when checked it sits around the 98 mark when the car is off and randomly goes from 20-60 whether it has a load on it or not. It has a fuel damper along with the fuel pressure sensor and from what I've been able to find out were only installed on certain models of the 02-03 Vulcan V6. Question is, would the damper cause that crap? and can I just switch out the front fuel rail for one that doesn't have it?
