[s-cars] Problem SQ/KW

[Frederic L'Huillier]

Colin,

My friend Norbert had similar problems with his SQ.
Spark Plug cables and other electrical components were changed (included
rare distributor) and the problem was solved.

And no, I will not ask to have the car for one year !!!!

Regards,
Frederic

Colin!
The boost on the SQ is solely controlled by wastegate spring stiffness.
There are no frequency valve on this system with the LH-Jetronic. If you
are refering to the boost-gauge inside the instrument panel this is
electric controlled by the ECU and is very inaccurate. The stock max
boost on the SQ is 1,05 barg(showing as 2,05 on the gauge) on the
European models. I do not believe the check-engine light is related to
low boost, but low boost is a function of malfunctioning sensors.

I will try tomorrow to disconnect the sensors(air temp,water temp,MAF
etc) on my car and see if I can provoke a similar situation as you have.

Is the US cars equipped with both catalysators and O2 sensor?


Best regards Joern,MTM RS
