Hey, sorry I could not write back as I was busy with school and work.


I ordered an APC valve, it should arrive by Wednesday and I will try it on ASAP and test it. I think it is APC valve, because it causes bucking as you saw in video and also sometimes there is underboost.

As for the jerk, which I have not recorded a video on it, could be a Clutch issue. I replaced the clutch 6000km ago. I had bought 2 clutch at that time, and the mechanic put the wrong clutch in it.
Because when I release the gas pedal and then accelarate the car jerks. BUT WHEN, I press the clutch pedal little bit and then give gas it doesnt jerk.

So it could be the clutch or something else. I'm not sure.

The clutch he put in is the same size (inner and outer), but the clutch he put in has a different shape inner diameter and its in silver color. Check out the attachment and let me know what you think.

I got the APC valve and I tried it right away. The problem is gone but there is very little boost. The "bad" valve used to give me extreme boost (orange) and it would do bucking.

But the new one is OK, but there is very little boost.. the boost is in the middle (yellow?)

Do i need adjust the pressure somehow?

First make sure you don't have a leak somewhere, like a loose hose, or one with a hole. Then from there, you can adjust the base boost via the rod on the WG actuator. The more you tighten it, the further in it goes, thereby increasing base boost. However, don't crank it in too far. A turn or two and test it. Having a real boost gauge helps to know where you're at, since the factory one is mostly useless.

Thanks for all your help saablink members.
I finally saw the WG and the rod. tried to adjust it but couldnt. So...

I decided to stop spending $ on this 93 saab. Its just too much problem.
Sofar ive fixed. the clutch (1300$ including labor and clutch), alternator (220$), Upper engine mount (120$), APC valve (205$), tranny mount (20$)

I still have parts for 2 lower engine mounts, + outer tie rod end (getting it fixed this friday then alignment!) .

Hey Im back with good news!

So 2 days ago I went to Aktive Motors in Oakville, Ontario. I had chance to meet the owner Christian (a very good guy!)
I had the following problems b4 i went there. TCS CTRL + ANTI LOCK, and SRS light was on.

The SRS light was resetted and light never came back.
The TCS + antilock light was a bad MAIN RELAY( its under the hood). I changed the relay and the lights disappeared.

He also told me that the Jerk on the car might be the vacuum hoses. So today I changed 98% of the hoses and the "jerking" problem almost went away. I think the problem might be lower engine mounts. I will go back to Christian to get them changed b4 January.

I also cleaned the Throttle Body, now it Idles a lil better.
