Two years ago, my car would occasionally shake when changing gears, notably first into second and around 60 mph. my check engine late came on and spit out the camshaft sensor code. I got it replaced and didn't have any problems with it again until 2 days ago, the car shuddered shifting gears like it did back when i had issues with the camshaft sensor. i had the check engine light checked and sure enough i'm having to get it replaced yet again.

Drops one or more cylinders intermittently. Occurs during acceleration, steady state interstate speeds, going around corners, initial acceleration and idle. Will do it repetedly during a single incident or may not do it for a couple of months. Dealer tried to fix oil leak at front of head or cam sensor at low mileage, and it started after that. Eng light kept coming on. Code read cam sensor.

Occasionally would fail to start for a few seconds. Wait a minute and would start fine. Check engine light finally showed up and fixed by replacing cam positioning sensor.
