Saab 9-3 stalling problems

Filed Dec 3, 2020 · Engine, Fuel system · 160,000 miles · NY

My vehicle doesn't start/idle well in the cold due to the air intake manifold bolts slowly becoming loose. **when driving and shifting** the vehicle cannot handle the extra unclean air entering the system and will stall out while going anywheres from 0-60+ MPH, once the engine shuts off all power steering also shuts down. The secondary issue is an acceleration problem because the seals on the air intake valves into the combustion chamber have become faulty resulting in cylinder misfires and a high amount of vibration intermittently while driving, the symptoms come and go with increasing frequency as time goes on. This secondary issue ties into the first issue because of shifting with a standard my vehicle today (12/3/2020) shut off while driving 7 times to and from my job.

My car wouldn't start so I replaced the battery and the crankshaft sensor. It drove fine and then I parked it and went out a little later and it would jerk and try to stall while I was driving, sputtering like I was running out of gas. If I pressed the accelerator, it wouldn't accelerate and then it would surge forward. I ran some errands and it drove fine. After my final errand, the car struggled to start but did and idled really roughly. I put it into gear and it died. I couldn't get it started again. After reading other posts, this seems like an issue with these years and veey dangerous.

I brought my 08 saab 9-3 to a shop for a compression test cause it kept stalling when I would go to start it, it's an automatic. I was told my intake valves were wearing down and it's due to gms faulty valves. Yesterday my car started ticking while I was driving and I lost almost all my power, come to find out my valves were about to snap. Now I'm making payments on a car I can't drive and gm refuses to fix this issue and there are multiple cases of this happening to 08-10 saab 9-3 with the gm factory valves.

Rough idle and start on cold starts. This issue is well known in the saab community due to gm putting weak material in factory fuel injector valves. Engine loses compression until car is warm, but may result in stalls or limp mode

Fuel pump deficiency. When I start the car in the morning to warm up before using it I notice and ear that it stall. After a second it accelerate to a normal RPM. It happens all the time since new (2010). I never received a fuel pump recall notice!

Misfires when cold, resulting in rough low idle speed and possible stalling after cold start.

The headlights in my vehicle started flickering and shut off while driving in the dark a few days ago. After safely parking the car, I investigated and found that the housings are designed to be unservicable but I was able to investigate and found that nearly all of the internal wiring shielding had cracked and fallen off (please see attached photos, I appologize about the quality). The headlights failing without notice created a very dangerous blackout scenario which could have very easily resulted in serious injury and/or death due to manufacturing defect and by no fault by or prior warning to the operator. I was lucky!

Vehicle stalls for no reason. This has happened while driving on the highway and during routine trips through streets with stop lights and stop signs. Check engine light comes on intermittently. Has been inspected my numerous mechanics and cannot find a problem.

Recently, while starting the car it started up very rough. A few weeks ago the check engine light also came on and the mechanic told me there was an issue in cylinder 2. We replaced all spark plugs and coils, and the issue did not go away. In addition, the car has also started stalling randomly. Luckily, I haven't been driving at high speeds when this has happened but it's now shut off about 7 or 8 times in the last month. Been wondering if its intake valves, fuel pump, powertrain control module, camshaft timing... Sounds like lots of other people have experienced similar issues and hoping mines not because of the intake valves. Please email [xxx]@hotmail.com if you have experienced similar issues and know the fix. Car is a manual transmission.
