well after racing a friend and hitting stupid fuel cut i think my motor is finally gone. right now it idles around 400-600 it sounds like my car is street ported or something it idles lumpy and the oil pressure is below 30 at idle.also it has no power below 3 grand but im not sure if its my turbo too because i tested it after i can be in 4th give it WOT and when it starts going the boost goes all the way up and then just drops like 3 psi then makes its way down not slowley but it just drops 2 psi at a time, although im reading this off my stock boost gauge. what do you guys think? oh yeah and im also gonna do a compression test tomarrow to find out. then i'll let you guys know

 

My 7 has a blown rear, and it wont do much below 3 grand. To start it you have to feather gas up to 3000, then above that it runs fairly normal. My guestimate is that you need to start ordering some rebuild parts.

Do the quick test

Remove the lead plugs and turn it over (w/o EGI fuse).

That will be enough to let you know what's going on..
