1999 Saab 9-3 - Acceleration Problems

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.

Solving 2001 Saab 9-5 ABS/TCS/CEL Problem -EricTheCarGuy
Visit me at: http://www.ericthecarguy.com/ This 2001 Saab 9-5 came in with just about every light lit up on the dash. The first code I pulled was a P1625 for the CEL which indicates a communication error between the ABS unit and the PCM. After looking into this code I found out this is a common problem with these Bosch ABS units. Rather than purchasing a new unit however I decided to send the existing ABS unit off to BBA Remanufacturing for remanufacture. Some of these units require that you pair a new unit up with the PCM, mine was one of those so sending off my existing unit made the most sense because if I had just gotten a remanufactured one I would have had to program it to work with the cars PCM. This took a bit longer but it saved me quite a bit of trouble in the end. Here are some useful links mentioned in the video.

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. http://www.ericthecarguy.com/forum/default.aspx --- Click below and Stay Dirty Visit me at EricTheCarGuy.com http://ericthecarguy.com/ Visit EricTheCarGuy Forum http://www.ericthecarguy.com/forum/default.aspx Visit my Facebook Page: http://www.facebook.com/EricTheCarGuy --- Stay dirty ETCG Due to factors beyond the control of EricTheCarGuy, it cannot guarantee against unauthorized modifications of this information, or improper use of this information.  EricTheCarGuy assumes no liability for property damage or injury incurred as a result of any of the information contained in this video. EricTheCarGuy recommends safe practices when working with power tools, automotive lifts, lifting tools, jack stands, electrical equipment, blunt instruments, chemicals, lubricants, or any other tools or equipment seen or implied in this video.  Due to factors beyond the control of EricTheCarGuy, no information contained in this video shall create any express or implied warranty or guarantee of any particular result.  Any injury, damage or loss that may result from improper use of these tools, equipment, or the information contained in this video is the sole responsibility of the user and not EricTheCarGuy.





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 will throw.





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!
