ok. i think i have fuel cut. i try looking it up but it just seems like there are so many forums out there that i can't read all of them. so maybe someone who has had the same issue can help.
So i decided to go fast on 3rd gear on the expressway, went down to about 45mph and put it in 3rd. hauled it to about 6500rpm and switch to 4th and went all the way to about 7k rpm and then let the gas go and it just turned off on me. turned it back on and it would turn back off. so i pulled over and checked it out. everything seemed normal. turned it back on and still turned off. had to give it gas so it could stay on. it shook all the way going home. so i had to drive home which was about 20 miles away but all expressway. so it was bucking a lot until i drove on the expressway. once on the express way i had it on 5th gear around 3k rpm and it drove fine without any problems. but once i got off it , it started acting up again. the next day i took it to a mechanic who has fixed my car before and it drove good on highway but once again sucked when i had to switch gears in city. so he saw the air hose that was loose from where the turbo is connected to intake, tightened it. and it now at least stays on. but when he test drove it it did the same thing. idk what it could be. i am thinking boost leak somewhere . but could i have messed up my turbo or engine?? how would i know. its a 98 mitsubishi eclipse gst. running 15psi with upgraded fuel pump and injectors. replaced air filter and fuel filter. spark plugs and wires bought about 4 months ago. any advice would be appreciated.

.. yeah thats what i think. but the mechanic thinks its the maf. so he is ordering a brand new one and is trying it out to see if it works. idk. but i will have to check myself. i just want her back.
