Couldn't resist.
No, we are not here to throwing
bones 
then why with me, why go back to the newbie, is there something wrong with me or the engine error

I saw the activities of the old people, commented a little but they got on the move faster

I just look at your
post history. Most of the post you're posted in the ANN threads and its filled with bounty reports and annoying big images. So its quite obvious why you didn't receive any merit.
Old people have the higher engine capacity like V12 but seem like the error is in your engine. It's time to change the engine or the entire vehicle before you're going to hit by some of the old member or mod
If you're considering about the modifications, Read this
manual and then you can move fast like the oldies.
