If you want help, stop starting new threads. Create a post that details the problems/symptoms you are fighting. Give us a little history on the issues, etc.
Then, let's get into what's going on. I see you have created several threads and sometimes that is appropriate - but to diagnose a car, we've got to pack the information in ONE thread, and best is not to tag on someone else's thread (tho newbs do that often, its not always a bad idea but it's best just to start your own thread).

I doubt you need a new engine as well, that sounds like the utterance of someone who simply can't diagnose the car. MOST of the time, the issue with these engines is NOT the engine, its a module, a sensor or a bad fuel pump, and you know that (I can tell) as well as any of us do.
