New Member Question
I have owned a 99 156 1.8ts for a year now and have a problem with eratic idiling. At road end it bounces between 500 - 2000rpm sometimes stalling on me. It has become very dangerous to drive.
I have changed the MAF about 6 months ago it didn't cure it. I also changed the Lamba probe to no avail.
A friend of mine linked it up to a diag computer and the following code came up - 1173, Self adjusting Parameters.
Can any one help?
Not it has also become very very sore on petrol?
