i have a 1990 audi 80 i bought the motor is from a 87 5000 10v mc1 turbo
i bought this car it would not idle due to vacuum leaks.. i went through all the intake piping and vacuum hoses and am getting around 18psi vacuum while idleing at aprox 850-900 rpm

i just changed the oil and barley drove it the vacuum lines and oil have tons of gas in them. also while accelerating it cuts out verry mad when mid to high accel.

from what i could find it could be the fuel pump/filters or FFV from what i am seeing it uses the FFV instead of the FPR.

i have new filters coming tomorrow and i will be puting those in once i have time

side note this car sat for 3 years before i had bought it to use for rallycross

i cant find in the bently book that i have on checking the ffv but im sure its in there just cant find it. where do i go from here?
