2013 2.5 SE Jetta had rough idle and upon start RPMs would drop to zero and car would shut off, but then if you start the car and give it gas, you could get it to idle and and maintain RPMs the RPMs were bouncing about 100 RPM up and down. and the idle was a bit rough. But upon driving, the ride was extremely smooth. I was getting a camshaft sensor code and a crankshaft sensor code. I changed the throttlebody and both sensors and the RPM stopped bouncing at idle, but upon starting the RPMs would still go to zero and the car was shut off. but now the car idles smoother and drives smoother and now checking the codes I am getting a timing belt stretched code. Please help this car only has 120,000 miles..
