Could it be that you're flooding the engine?
Not really sure here.. just a shot in the dark.

by the way the unflooding process is different for an S4 ('86-'89) so be sure to check up on the right one.

push it down a hill.....



No, seriously, push it down a hill, pop the clutch in first and give it some throttle once it turns over. It may take more than once if you've flooded it bad enough. Best way to do it.

EDIT: Oh, and get it going pretty fast to do it too.

Injecting Automatic Transmission fluid will build the compression when it's cold out and heavily flooded, then after you do that, put the antiflood switch in. The link above explains the procedure.

pull EGI fuse......

turn it a couple times to burn off excess fuel....

put fuse back in and start 'er up.....you may get a little smoke out your pipes, but it should go away after a couple minutes

good luck!

PS......you shouldn't even really have to give it gas when you are trying to start it, and if you do just barely press the pedal....that's how my 86 gets to gettin'!
