Hi, my name is Viktor from Irkutsk, Russia (Siberia)
my 95 SAAB 9000cde 2,3T (hpt) 200h.p. (72000km) the acceleration
became too slow
these works were made correctly:
1. all filters were replaced (fuel, air)
2. new DI cassete, plugs(original)
3. injectors were cleaned
4. the air inflow (and containment of intercooler) was checked- all ÎÊ
5. CO= 0,2% (850rpm), 0,2% (3000rpm)
6. BPC(APC) valve is OK
7. turbo pressure- 0,7bar
8. "check engine" indication doesn't appear, err codes in memory not present
9. there is no consumption of oil, and no oil in turbine.
10.there results of diags are the following:
O2 sensor- max 0.98 min 0,01-0,12
MAP- 0,8 min, 2.2 max
Temperature sensor- 0,4kOm
TPS sensor min 0,10-max-2,59 (linear)
Temp sens(?) - 1,62 kOm
linear fuel pressure (with vacuum) 2,6 bar
(without vacuum) 3,1 bar
max fuel pressure (before ramp) 6,5 bar
compression: 13,5 13 13 13,5
depression in the inlet manifold (ÕÕ) - 0,74 kPa
but i still have these problems:
1.with the pedal pressed in full, acceleration is worse that with the
pedal pressed 2/3
2.when the BPC valve is off (central hose is deactivated) there are no
cutoffs of trionic, when the pedal is pressed 2/3--there are cutoffs.
3.þáêè of spark-plug are black, while the central isolator is brightly
white.
what can it be? MAP sensor? O2 sensor? trionic?
unfortunately, there's no saab center in my city :(
if you can help me to find the malfunction or advise something, then
please write to vigol(at)sel.ru. Thanks in advance!
