OK, The problem has been fixed. after checking all the electrical parts (voltage, power in and out , gas licks, etc) we started checking the timing, when we looked to see the marks and check if they were in the right position we realize that it was off ( the timing belt was changed last year but there was no problem for 6 months) , we then took out all the belts and checked why it was not in the right position, well the problem came to this:
the key in the chanckshaft was broken and the crankshaft got loose, the car had this problem for about 3 o4 weeks, enought to waste a good part of the crankshaft, there was only 2 options, replace it (lots of money) or just weld the part. I took the second option, after welding the part we just align it and put all the parts toghether again. the code p0340 ( camshaft positioning sensor ) got away, the enging started right away with no problems and the engine runs fine now. total spend money in parts that did not have nothing to do with the problem: $220.00 time spended in finding the problem and correct it: 8 hours a car running with no problems with this winter warning( Omaha March 20 2006)
I will not say priceless, is just WONDERFUL!!!! adios!!!
