I feel a little confused and out of options here so it will be great if someone can help with the issue! To start heres a little back ground I bought a new to me halfway running 2005 9-3 little turbo. Ive owned a lot of 9-3ss and never have dealt with this. When I got it the car ran like garbage. She misfired, ran very rough at idle, and had half boost but any amount made the car shake terribly, was still able to limp home. Got the car into my shop and checked for codes. The car stored P0201,P0202,P0203,P0204,P0245. Doing some research and through past experience with other vehicles having similar issues I came to the conclusion the ecu was fried. I sent off the ecu to be repaired. While the ecu was being repaired I replaced the plugs checked the resistance of all the injectors, and replaced the battery. ECU comes in plug everything up check for codes no codes present. Car fired right up ran rough. Checked myself over and decided to check the coils. Coil 2 was replaced with an import direct part. Car runs perfectly no misfire code drove the car about 30 miles and it was running and driving like any other Saab I had. Came out of the store 20 mins later turned the key and it just cranked. Waited 15-20 mins it just cranked again, then I held the gas pedal down while cranking and it fired right up and the check engine light was instantly on with P0201-0204 and so was the P0245. The car was running fine nothing would indicate an issue other the the CEL and that its running on half boost. I dont want to throw more parts at it so I really need some input. Trying to save this little Saabs life!
To recap:
-Codes P0201-P0204 and P0245
-Codes before repair are present 30 miles after repair after not starting until holding gas pedal down while cranking
-Ecu repair was completed by Your part source saying the injectors and turbo control chips
- checked injector resistance 1234 in order 12.7, 12.5, 12.7, 12.7 to my understanding this is within spec
-Replaced cyl2 coil with import direct part claiming it was specific to the Saab and didnt not cross reference with any other vehicle
-New battery
-New plugs
-New valve cover gasket
-replaced main relay #4 and fuse #4
-Car currently drives smooth but is under powered and the boat gauge goes to halfway at most
My only thought I have left is when the ecu failed it took all the injectors and the boost solenoid with it I feel it would be running a lot worse if that was the case though. Not sure what to do and do want to order a set of injectors or a wastegate solenoid without some sort of confirmation.
The car has a few other faults that I’m not sure would affect this but I will add it in here. The SID is stuck on outside temperature and you cannot change it. If you hit customize you can scroll perfectly through all the menus but just cant go through the different trip functions. The radio also doesn’t show anything on the SID and has no audio for the turn signals I’m blaming the amp1 haven’t looked to far into it yet. What’s odd about the radio situation is when you start the car it does something rather strange on the SID (see attached picture)
