    Hi, I have a 9-3 2000my, b204E stage 2, apc 7 converted car and each time I hit the pedal to the floor, around 3,5-4k rpm I'm getting overboost and fuel cut off. - It's not possible that apc is faulty, I replaced it to another t7 - the same thing - I tried to find any vacuum leak but no luck...
  2. Saab 9000 (1984 - 1998)
    I posted a few weeks ago about loss of power on my 1994 CSE 2.3lpt, which turned out to be the wategate actuator rod dropping off. Having refitted it, all seemed well, except that I have noticed a few times (nearly always) that when I floor the throttle for a quick blast, there is a sudden jerk...

    Hi guys, after being without an aero for a whole 2 years, i bought another 2day. A few little things to sort, the 1st of which being the overboosting problem it has. Full throttle in any gear is enough to send the boost needle right through the red. After looking through the comprehensive...

  5. Classic Saab 9-3/GM900 (1994 - 2002)/Conv ( -2003)
    Hi, I apologise if this has been covered before, but I couldn't find anything relevant in my searches. I have a 2000 Model 93 185BHP. The original turbo gave out on me a month or so ago (worn bearings), and I managed to locate a second hand turbo with a six month warranty from Simply Saab in...

    my 97 2.3 lpt has started to overboost again. ( Car has some sort of tuning stage 1 i imagine done to it with increased bhp +acceleration before i bought it). I fitted an apc valve recently which cured variable boost when cold and rextored the car to full mode tested apc 2.9 and 3 ohms...

    I haven't been very active on this forum for some time but I now have a problem I need some advice on. On friday morning on the way into work the car (96 2.3FTP) started overboosting. It will run into the red section until the ignition cut out comes in. It rained all day Saturday so I left...

    I've got an Intermitant problem with the engine cutting out for a split second when accelerating hard. I had a new DI cassette fitted a couple of weeks ago, as I was having the above problem plus rough running & poor fuel consumption. The car has run alot better, but It still cuts out when I...

    I've had a drop in performance (and boost pressure) on my 1999 9-3 for about a month - see Boost on 9-3. Having shortened the actuator (6 turns in all!) performance didn't increase and boost only increased slightly. Yesterday, (with no adjustment for 1000 miles) boost went right of the scale...

    I have a 1994 9000CSE 2.3t(200bhp)with 130k miles. There seems to be a boost problem. On full throttle, especially on kickdown, the boost guage needle goes into the broken red zone and the power is intermittent as a result. If you smoothly and slowly apply full throttle it does not happen...

    Sometimes when I put my foot down and accelerate, the engine seems to hit a limiter or something and judder violently and then carry on again. It feels like if it is overboosting like what I get in the Evo sometimes when the weather is cool. Is it the same case with my Aero? I also find that...

    I remember someone posting about this before and I did a search and found it, but there wasn't a definative post as to the problem. On the way to the Southern Saabscene Sequel, I started to get a pronounced stutter as the boost got into the broken red/sector, with the needle flicking up and...
