My saab started stalling (the engine acts as if it stops running, and then starts running again). This causes the rpms to fluctuate (sometimes going down 1500 rpm before coming back up). However, if I let the engine idle, there is no stalling. The longer I drive it, the worse it gets, until it stalls when slight pressure is applied to the accellerator. When I turn off the car and start it back up, it runs normal for a little bit. This problem has been getting progressively worse and now the car isn't driveable.
Also, when the accelerator is pressed hard from idle, there is a dip in the rpms. However, when in park I can raise the rpms to any level and it will stay there without fluctuating.
The computer is throwing the code P0108, the map sensor is showing higher pressure than expected. I have replaced the map sensor and all vacuum lines connected to the throttle body (they were in bad shape). After doing both of the above, the car seemed to work fine, then 30 miles down the road it was back to the same problem. After this I started throwing parts at it, and replaced the fuel filter, the fuel pressure regulator, and the spark plugs, I also cleaned out the throttle body. These had no effect. Just now, I used a baby snot bulb connected to turbo bypass valve to test for leaks, but it didn't seem to be losing vacuum.

Leak down testing
I get a lot of questions via email and over at the forum about the steps to
take when you encounter a performance issue like my Subaru's hesitation
issue and I often feel like I sound like a broken record when I cover the
basic steps that I cover when encountering a situation like that. My main
point here is that if you have a performance problem and you're going to
throw parts at the problem start with the basics before you to off and
start replacing sensors that you suspect are a problem, if you don't have
evidence of a faulty sensor then don't start there start with the simple
tune up items and check for vacuum leaks and air leaks as I've shown here
and I believe you'll have better results and save yourself some money in
the process. In short the rule of KISS applies, Keep It Simple Stupid.
If you have questions about your own engine performance issues head over to
my website and either ask the search function or ask the forum, we'd be
happy to help.

More Problems With the 2000 Saab 9-3 (Smoking, Test Drive, etc.)
Well many of you have seen all the other videos on this car and seen that
we replaced the turbo in it a little
while ago. After sitting for an extended period and battling to get it
started with a dead battery, when I took it for a drive it started smoking,
more and more. Today, 1 day later after I drove it, we started it up and
no smoke was to be found. Weird, we'll have to check it out more to make
sure everything is right with it. but like I said, today, everything was
totally fine so idk if the oil/gas mixture got screwed up or something from
sitting so long with little to no gas in it (had to fill it up before the
drive) or what. We shall see I guess! Let me know what you guys think!
Blown Head Gasket Saab 9-3?! Start Up With LOTS of Smoke
Well a lot of you probably remember the 2000 Saab 9-3 Hatch back that we
had at the dealership a couple of months ago. Well something happened to
the engine to where it just billows an un natural amount of pure white
smoke! They brought it back so we can get it fixed for them. In this
video I try and assess what's going on and see if you all have any
suggestions on what it could be before we send it to the shop. Dad also
pulls it around and sees for him self. we're thinking it's a head gasket
and maybe a motor mount or a tranny mount. Post below what you guys think
it is and I'll let you all know when we find out. You will see what I mean
and how bad this thing is haha, enjoy!

Is Your Car Hesitating. It May Need A New Throttle Position Sensor
Scotty Kilmer, mechanic for the last 46 years, shows how to fix a car that
hesitates while accelerating. It can be as simple as a bad throttle
position sensor, which you can easily replace yourself. And, If you like my

Saab 9-3 bumper and headlight removal
Removing the front bumper and xenon headlight from a Saab 9-3. This is
necessary if you need to replace the xenon ballast. It is not necessary to
remove the bumper or headlight assemblies to replace the bulbs. But, now
you know how, if you ever needed or wanted to. / I've DISABLED COMMENTS! I

How to reset a Saab B235R throttle body from Limp-Home-Mode
This is a very easy how-to on resetting a throttle body from limp-home-mode
for most OG9-3 and NG900's (and some 9-5's). The dealership will charge you
LOTS of money for this simple 5 minute job. You will also have to have the
check engine light reset, but you can get that done for free usually at
Auto Zone or Advance Auto Parts, or if you have an OBDII scan tool,
clearing the codes will clear the code & light that a reset throttle body
1999 SAAB 9-5 Whining noise (The dreaded sludge?)
A short clip of our SAAB 9-5 2.0T which has developed a rather annoying
high pitched whine until warm.
This problem (from what I've been reading) stems from oil sludge building
up in the sump which will eventually starve the engine of oil. Heres to
hoping its not quite that serious.
The car is a 1999 and has 156k miles on the clock.
~ 700hp Turbo Saab, 312kmh (194mph)
Extreme turbo Saab + 300 kmh
Many viewers have misunderstood this video, so I explain it a little:
-Speed at finish line (1mile/1609m) is measured. Time is not measured.
-First Saab does 1st and 2nd gear with ~half throttle. Second Saab has
limited Boost for 1st and 2nd gear.
- three extra seconds between 0-100kmh typically means ~30meters wasted.
But three extra seconds used in speeds close to 300kmh, means almost
Here is equally powerful RWD cars (if not even more HP's) These RWD's are a
lot faster between 0-150kmh, but
these Saabs are faster from
150kmh-300kmh. You get the point when you compare speeds at finish line.
-A Saab 9-5 driver pushes a little too much throttle @3rd gear and looses
traction. He lifts a throttle and pushes it back, but too much again and
then he gears up 4th, a bit earlier than planned. (optimal is@205kmh).
Earlier that summer I broke one gearbox when pushing too hard on 3rd gear.
With new gearbox and at later event, I drove very gently on first three
gears to avoid breaking it again. I pushed WOT for the first time on 4th
gear @ 190kmh. You can hear it clearly on following video. Engine tone
changes totally around 200kmh. Incar video is from 299kmh pull (at 1 mile
race) Something happened to camera during the run. So I didn't get any
incar video from a 305kmh pull. To see that run from the start line, please
see my other videos.
Here is incar video until camera dies. Start is @1min.
