hi, first of all my car is a 90quattro with an aeb turbo motor in it, it has a t28 turbo, 3" downpipe, 3" maf, calibra turbo injectors(pulsar gtir to go in if there not up to the job) and a front mounted intercooler. it has an a6 1998 engine wiring loom and and matching ecu(2 plug), however it has the original maf and ignition amplifier to the engine(which originally had a 5 plug ecu).
so i've had the immo removed and it fires up and idles. but when rev'd up it seems as though the ignition is been cut off and then revs a bit then cuts again, pretty sure i had the same problem with my a6 1.8t a few year ago but that was down too the pipe from the intercooler to the throttle body popping off, i have double checked and there is no air leaks, so my thinking is wrong maf, and possibly wrong ignition amplifier(are they different?)
unfortunately i don't have the diagnostic port wired up yet so thats not an option at the minute.
finally i have a pipe that has a check valve(i think) comes from the inlet manifold underneath, just behind the throttle body(towards the engine from the throttle body) and loops round to a take off again on the inlet manifold but to the rear of the throttle body(looking at it from the front of the car) it just loops from the inlet back to inlet so im assuming there should be something there?????
any ideas? cheers
