I just bought a 96 Ford Taurus 3.0 liter with 116k miles about 2 months ago. The service engine soon light came on a few days after i bought it. I had the computer scanned and it showed code P0340 i believe. It was for a camshaft position sensor circuit malfunction. I brought it into the shop and had the sensor replaced. The mechanic erased the code and all was well for a week or so. Now the light is back on with the same code showing. I talked with the mechanic and he said it is very common on these cars to have to replace the camshaft position synchronizer and that it would be about $250 to replace.
Does that sound right? I don't know a whole lot about cars and he knows that. He is also trying to get me to replace the timing chain because it is recommended at 100k miles and that will be about $800 which includes a few other parts that should be replaced while doing the chain.
I don't really want to mess with the chain because my dad told me if it ain't broke don't fix it especially if it costs $800. Is the 3.0 an interference engine? I don't want to risk damaging the engine if the chain breaks.
Is there any other common problems that i should take care of? My cars go through a pretty hard time i deliver a rural mail route. The route is about 100 miles a day of stop and go driving on dusty roads. I really like this car and plan on driving it for a few years so i would like to take good care of it.
