Yes, i searched but didnt find anything with the exact symptoms

1988 S4 TII - Second motor in the car....

On cold start up (i cant get it to run long enough to warm up) the car runs ok for a few seconds, however when i touch the throttle at all in attempt to rev it or move it a little the rpms drop rapidly(bogs down and stalls). The AFM and connector looks to be in good shape, there are no codes present and it is NOT flooded. I took the plugs out and cranked over etc to clean everything out. When i parked the car before the winter it seemed fine, however i JUST installed the motor before i had to put it away, and didnt have alot of run time on it.

Any help would be appreciated, thanks for your input and time!

make sure the AFM and all the piping behind it is secure. that problem has always been AFM related for me

 

my friend was having this problem, its a s4 turbo with s5 internals. It turned out to be a bad fuel pump, the car will start, but the slightest touch of the pedal will make it bogg out. After he put a new fuel pump the problem went away

 

Ok, i am going to try another AFM... i am sure it is not the piping... its complelety sealed.

Thanks,
