So my 2000 GTP's heads up display shakes a lot (the display itself shakes - the dash, steering wheel, etc. don't) at about 1900-2000 RPM on the highway and only then. It doesn't shake if I'm coasting or WOT. What could be the cause of this? I know the little exhaust piece that connects the downpipe to the resonator is rusting (as is the resonator itself) and those are causing a small exhaust leak/light vibration throughout that part of the car (I can feel through the floor). Could this be the issue, or is more likely that something is loose in the HUD unit? Has anyone else seen this before? It's not a major concern, it just bugs me a little bit and I'm curious to see what people think. Otherwise the HUD works fine. I can take a video of what's happening and post it if it helps. Thanks!
