I have 84 audi 4000 s auto....... been told by several mechanics its the fuel distributor (?).... I cannot afford to take to dealer ....it is a 1984..right...
I have found several o/l salvage dlrs across usa who have this part. They say it has been tested... Is this normal practice or am I spending several 100 foolishly . car is in good shape and under 50 k milage. I have had this car 4 yrs and before this have spent money to replace all fluids and wiring. and it ran good up to now. other then stop and go city driving that causes it to overheat.
also have been told by salvage yard tech it could be wrm up valve. I dont know this part...

many things can cause this. the most common problem would be that the timing is slightly off. (fixed sometimes by adjusting the distributor) it could also be a bad fuel pump (or clogged fuel filter) this would allow enough fuel to run the engine in park but not enough to run the engine under stress. clogged air filter could also cause this (not allowing enough air into the cylinders). I would change the air filter and fuel filter. then crank the vehicle and slowly turn the distributor (finding the best idle position) then see what happens. lastly replace the fuel pump.
Yea , those crossfire injection vettes can be a bear sometimes . I had dealings with them 84-85 - 86 working as a tech at a chevy dealer . Don't remember much about them , haven't heard anything about them for long time .
How's the fuel pressure ? Have you put a fuel gauge on it ? I would imagine you don't have a Tech 1 scan tool ? What's the map sensor voltage at idle ?
First- Codes do not tell you what to fix. You already found that out.
Second-Logically,why would a speed sensor on a trans cause a stall. The speed sensors and there are several.produce outputs on shaft and drum speeds in the trans. Those signals are part of the PCM input strategy for shift points. At low speed,your not shifting,your stalling.
There is no such thing as baffled. Lacks your vehicles system knowledge, maybe!
Do you have a clean fuel filter?
Do you have fuel pressure during the stall?
Do you have fairly new spark plugs?
What does the data for the Throttle Position Sensor,Mass Air Flow Sensor,Egr Valve Etc look like before the stall.
Got vacuum leaks?
Now --you either need to leave the vehicle at a shop,until they repair it
-Find a good tech at another shop that knows your vehicle
Or get the manuals and start on a life long persuit of auto technolgy. I like the last one.
since the car is so old i would suggest you hitting up your local salvage yard and buying the model and mass airflow meter you can get all this stuff for $20-30 if you remove it yourself , also buy you a audi service manual at parts house for $15 will show you were this stuff is located. its not the technical way of doing diagnosis but if you cant afford a diagnosis? tyr repacing the stuff that could cause the problem you might get lucky? the fuel injectors will have to be proffesionally installed with new orings ?
O.M.G. THE BATTERY SHOULD HAVE BEEN ABOUT 80-95 BUCKS. AND THE TERMINAL IS ABOUT 5 BUCKS TO BUY. TAKE THE CAR TO AN AUTO PARTS STORE THAT CHECKS THE ENGINE CODES FOR FREE.......MAKE SURE THAT THEY CAN CHECK FOR PENDING CODES AS WELL. IT SOUNDS TO ME LIKE A CRANK SENSOR. OH AND BY THE WAY, MOST AUTO PARTS STORES WILL INSTALL A BATTERY THAT YOU PURCHASE AT THEIR STORE FOR FREEEEEEEEEEEEE.!!!!!!!!!!!!..... PLEASE FIND A BETTER MECHANIC. I HOPE THIS HELPS YOU. THANKS FOR USING FIX-YA. BEST OF LUCK. PLEASE KEEP ME POSTED, CAUSE I AM REALLY CURIOUS TO KNOW WHAT YOU FIND.
were the spark plug gaps set properly with feeler gauges if they were put in straight from packet they need to be set to correct gap which could cause miss firing or it is possible the leads were not put back on in correct order and probably a good idea to reset the timing if you do not have a timing light pop into mechanic its a 5min job an honest mechanic at worst would charge you $10 .00 to do timing this would make a huge difference when starting of a morning hope this helps thanks glenn
