A6 1995/6 1984cc pet ABK manual transmission saloon.
There is a intermittant jolt/judder throughout the rev range.
At idle the eng can almost stop and then abruptly pick up again, this action has a similar signature to the intermitant jolt/judder within the rpm range.
It seems more like an electrical cut out/in, although it could be a fuel cut out/in.
At idle the action is quick. It does not seem to slow down slowly as a fuel cut out may do.
The engine seems to almost stop quickly and then with a jolt pick up quickly to idle.
At rpm above idle a jolt /judder is noticable which is less noticable at higher rpm.
In another forum it is mentioned that a spike was found at a coil.
Does anyone know how to test for the electrical spike using a multimeter?
It has been suggested that basic settings need doing, does this yr have basic settings?
Do these engines run at 90 degrees C?
I had put in a temp' sensor from another eng and it showed about 50 degress C on the guage.
Some yrs ago I self checked the sensors and found relay 30 (eng' contr'l relay) was damaged.
This could be an OBD 1 compliant engine.
It is very difficult to find specific info re this car/eng.
Got various bits of info.
Thank you for any suggestions.
