Last year car started stalling at red lights or in slow freeway traffic. Then I went 7 months without a problem. Last Saturday, traveling at 70 mph on the freeway, I lost speed on the freeway and as I drifted to the shoulder, lost the power steering. Turned out the cam shaft sensor failed causing 3 catalitic converters to melt. Big bucks later all has been replaced.

Cam sensor went out while driving at highway speeds and engine immediately stopped. Was able to restart but unable to keep vehicle moving at any speed over 20mph. Cam sensor had to be replaced.
