Specialist 928 Mechanic North NJ

Have a 1989 S4. Have replaced nearly everything possible and still can’t solver the issue of the car bogging to a stall or not restarting after being turned off. Have replaced most of the fuel system including injectors, new wiring harness. Need an expert service person to figure this out. Northern New Jersey. 
 

I can recommend Bob's Motor Works in Atlantic Highlands, NJ

He owns and knows 928s well.

Thanks Vm. Will give Bob a call.

Did you ever figure out what was the issue?

Apparently cleaning connections and grounds cleared up the problem.
