I'm obviously pretty new to this site, and very inexperienced when it comes to cars! I have a situation and here it goes, last august my timing belt broke on my '98 contour, ( 4cyl), i took it to a local shop and they did the computer test and it read obviously some timing problem and he opened it up and of course the belt had sheared three teeth! So he threw and new one on and called it good. I drove it home ( about 45 miles) and pulled into the driveway, and no sooner did it die again. Called the people up had them come get it come to find out it was the idler pulling bearing had blown apart ok fixed that the car was fine. Now in February the CEL came on and I had it checked at Auto Zone and it was the same code P1381, and i took it to another guy who looked at it and found that the bottom pulleyes rubber middle had slipped and the little tensioner arm that doesn't have to be put in until you first replace the belt hadn't been put in. He fixed that not even a month later the CEL came back on and I just now had it checked again at AutoZone, same code P1381. Now everything that I've read here suggests that I may need an engine oil flush! Is this assumption correct or should I be focusing on a bigger problem? HEEELP Please! I want to go into some place knowing a little about my problem so I"m not being taken for a huge amount of money! Thanks....
