misfire on the engine white smoke and smelling gasoline

[RoccoH]

But unfortunately, none of the above mentioned engines can be found in the 9-3 NG models.

Below are the NGP spark plugs, split down in the three different Petrol engine categories which can be found in the 9-3 NG models (please note that not all engine variants were available on certain markets):

Z18XE: BKR5EQUPA (0.6 mm gap) - 1.8i non-turbo (122 HP)


B207E/L/R: PFR6T-10G (1.0 mm gap) - 1.8t (150 hp) / 2.0t (175hp) / 2.0T (209 HP)
B207E/L/R Biopower up to Engine no. -11765305: BKR7ESC-11 (1.1 mm gap)
B207E/L/R Biopower from Engine no. 11765306-: PFR6D-10G (1.0 mm gap)
Z20NFL: BKR7ESC-11 (1.1 mm gap)
A20NFT: PFR6D10G (1.0 mm gap)


B284E/L: PLFR6C-10G (1.0 mm gap) 230 HP / 250 HP
B284R: PLFR6C-10G (1.0 mm gap) or DILFR7B10G (1.0 mm gap) 280 HP

Thanks for the complement !!

Oups you've made a little mistake gap is at 1.0-1.1 mm not 10 mm everyone have corrected by himself. I hope;-B

[RoccoH]

cheers for the correction

[ile2010]

you're absolutely right, i will not using others than original parts in this area, thousand of posts I've reading last month are all heading same direction, You fooled with that you're in troubles.
some useful infos found in forums not traduced in USA scales sorry for that ;-)
B204E/L/R:BCPR7ES-11, gap:1.00-1.10 mm
B234E/L/R:BCPR7ES-11, gap:1.00-1.10 mm

B205E:BCPR6ES-11, gap: 1.00-1.10 mm
B205E:M/01-> with Saab tuningkit FR6H-10, gap:0.90-1.00 mm
B205BioPower:BCPR7ES-11, gap:1.00-1.10 mm

B235E:BCPR6ES-11, gap: 1.00-1.10 mm
B235L FR6H-10, gap: 0.90-1.00 mm
B235R FR6H-10 or possibly PFR7H-10, gap: 0.90-1.00 mm

B308E:BKR7ES-11, gap 1.00-1.10 mm (Different from 4-cyl)

Note:
1) Since the spark plug is used as a sensor, the recommended type must be used, otherwise the "sensor reading can not be trusted".

2) Use only NGK plugs.

3) Electrode gap, use the values shown above. There is absolutely no truth in the myth "LPT 1.10 and Aeros 1.00".

4) Gap should be checked with a wire gauge.

5) You need a 16 mm or in inch, 5/8" spark plug socket.

6) Tightening torque is very important, too loose will cause the plugs to overheat.
4-cyl.28 Nm
V6:27 Nm.
Or, if using NGK (Saab) sparkplugs, first just nip the plug with your fingers, then tighten with 3/4 of a turn.

7) Tighten the DI with 11 Nm.

8) The myth that All 4-cyl can use BCPR6ES-11 or BCPR7ES-11 is not true.

9) Under some circumstances different plugs can be used, we run BCPR5ES-11 on some markets, due to fuel quality and driving behaviour. However, DO NOT
try to be an expert, just simply because you're not ! Stay with the official advice.

10) For highly boosted high reving engines BCPR9ES-11 has been tried,
however, if you need cold hard plugs like this, you may consider your choice of tuner...

11) Also BCR8ES has been tried, once again, it may not be the best choice...
The BCR8ES plug is physically different from the BCPR plugs, the gap is "more hidden" and this is not what a engine expert aims for. The gap should normally be deep into the air/fuel mixture.

12) Do NOT use iridium plugs.

Why not iridium, especially if NGK? Wouldn't the OE manufacturer spec them properly?

[swisssaabist]

because all peoples who's experimented others than recommended ones, experiencing issues with cassette or misfires and why spending more than needed ? for saying to others with a small mouth "you know..! on mine i have iridium ones so cute " do you believe NGK has tested these ones for days just for Saabs even they says it's compatible.

Good evening, I have the exact same issue but it s not all time I m cranking the car. Scanner returns P0201 and P0245. Removed the plugs ( which were replaced not so long ago) they look very black. I cleaned and put them back.
i also have an oil leak somewhere close to the turbo fixing to the exhaust manifold which causes smell and smoke close to the turbo Area. I guess those 2 issues are separated .
