Hi

I test all the components on the emission from the canister to the gaz tank.

I find out the air vent valve was frozen from condensation.

I just used a hair dryer to dry the condensation in the valve. Now it is working fine.

I do still have the SSS problem. It stall a few time since my last post.

I' m now working with a duty cycle tester and I built the code reader from Arthur Dalton design.

The first few code I retreive was more or less junk because I was testing some component and propably create does code.

Over the week-end after I erase the junk code the car stall again....

The code I retreive was code7 and code27

Code 7 = Rpm signal
Code 27 = Ignition contol unit

The procedure for both of this code seams to point tower the EZL(ignition control unit) as the problem. I do check all the component related to the EZL, crank sensor, temp sensor, coil, throttle valve switch, reference resistor and all wiring according to the procedure, they where all within the spec.

I do have one ground broken, the one from the intake manifold to the left of the wheelhouse under coil.

I took the decision to change the EZL ignition unit.

Will see tomorrow the weather forcast say -26 C°.
