My 1982 911SC was a perfectly running car while I lived in Houston. I moved to Calgary last December and have been having persistent CIS problems.

1) Car stalled on highway and was not getting fuel. Towed it home, emptied and cleaned the tank, changed tank screen and fuel pump. This fixed the fuel delivery problem.
2) The car would start cold but would not start it left for 20 mins when hot. At his point I changed the fuel filter, accumulator and all the injectors.
3) Continued to have hot start problems so I took the car in to an indy Porsche mechanic shop in Calgary. They diagnosed that the control pressures were too low and changed the pressure regulator in the fuel distributor. I was told the fuel lines were clogged and they cleaned them and WUR was operating as it should.
4) Now the car does not start when cold or left for 20 min when hot. The shop asked me to push the gas pedal in an inch to start the car. The car starts by cranking with the gas pedal pushed in but I can smell that it is too rich and cold idle is not like before. It would not go over 600-700 rpm during cold starts.

When the car warms up it runs really well. Stronger than ever before.

I know that I should not have to push the gas pedal to start the car. I do not have CIS tester and that was the reason why I took it to a well known mechanic. I bought a CIS tester from Amazon.ca but the quality was so bad that even the fittings within the kit would not smoothly fit each other. Returned it.

I am completely lost and do not know what the problem is or how to solve it. Have an appointment with another well known Porsche shop here. Not sure how good these guys are but I am not sure what I can do at this point. Appreciate any inputs.
