At this points I think I have found the problem, the tps that the mechanic change, was out of adjustment, the shake of the car has almost stop when change the engine mounts, the mini misfires I think thats something internal of the engine but I think I will live with that, also take out the whole throttle body and cleans it and all its passages, I will be updating what things have worked or not, thanks
