My GT has 125,000 miles. Several months ago, my car would 'hesitate'. I changed spark plugs abd the fuel filter with no change. Then I started getting the P0012 code. I took it to a diagnostic guy who told me I would need a new engine. He told me if I replace all the timing components, it would likely cause catastrophic engine failure. He has personally dealt with 4 of the 3V engines and 3 have blown up within 100 miles. Has anyone else had any experience with this? A footnote: he told me he did not want to do the work and only charged me an hour labor for 3 days of work. I also take good care of my car.
