Hello everyone

I have a bit of a problem I asked the dealership and they cant find the problem with My car
it started to turn off at random time that began to shrink in size from 1 hour to 30 mins to 5 mins now it will only run for 5 seconds and then turns off I had recently put the fuel pump from a 2007 S60 Volvo so i doubt that's the problem i checked the injectors and they seem to be clean sealed and in a good shape I would appreciate any ideas
some times the check engine light flashes a little then goes away and the message reduced engine performance comes up.

thanks in advance

 

a vac leak that's getting progressively worse, likely around your intake manifold where it bolts to the head.
re-torque the bolts and see if it gets better, if it does remove the manifold and replace your gasket.

that's my guess

 

thanks for the advice it turned out the problem was with the vac tube itself the restraint has shifting causing a leak thanks again
