Two weeks ago, after I sprayed the radiator with pressurized water from my garden hose, it FOR THE FIRST TIME started having a hard time starting. Mechanics looked for sensors the computer told them are acting up in the morning when it typically would have a problem - and they narrowed it down to 'Eccentric Camshaft Sensor [on the right side]" which they found wet. I found a strategy of avoiding start-up problems. They said that the sensor is not working fully. I found my own semi-solution: I simply turn the car on at shorter intervals (I turn the engine on at night before sleep - and I have no problem in the morning starting the car!). Could the Eccentric Camshaft Sensor be the real cause of my problem ?
