Hi Guys, Ok update and more help needed I have been lent very kindly by a good chap, a diagnosics kit, I have read the following faults in the memory since giving it a good drive. P0150 - O2 Sensor ahead of cat conv (cyl 4-6) P0300 - Misfiring damanging to cat. P0306 - Cyl 6 misfiring damaging to cat P1119 - Heating power O2S ahead of cat. bank 2 I then analysied the misfire read outs, and cylinder 6 was misfiring quite heavily, while Cylinders 1 and 5 misfired once (over a period of around a 5 minute drive) I then read the voltage of the O2 sensors over a 72 second period On Bank 1, the lowest voltage was 0.07 and the highest was 0.82. The values were shooting up and down at every samples rate On Bank 2, the lowest voltage was 0.13 and the highest was 0.24. The values stayed quite steady with every sample rate What are your immediate thoughts?? Many thanks Russ

Hi Loren, Smoke isnt the word, I would say more smoke, its like a white smoke. However, it does not seem to smell rich anymore, well not as much anyway. Do you think I need to take it for a good drive to get rid of the oil and see what happens? Cheers Russ
-
Guys, I have now replaced the AOS, cleaned the spark plugs (the bank 2 spark plugs were black, bank 1 were not to bad), put it all back together, started it up, but stil the same, if not slightly worse. Its mis firing loads, CEL light is flashing madly one things that has improved though, is it now idles at 850 and not 500 as before. Any suggestions guys?? Do I need to replace the O2? Cheers Russ
-
its ok, its all done, just give the spark plugs a clean down and clean the o2 sensors. If all is well, I will take the cats off and wash tehm out too at some point just in case, its its still bad, then will let you know Changing the AOS was actually not a bad job as I read in some of the posts, mainly cause I used a thumb screw jubliee clip in replace of the clamp style one, it was easy to screw up with the wheel off cheers Russ
-
guys, can you point me in the direction of this guide for changing th AOS, I cant find it, done a search on here
-
would this cause the misfiring on all back 2 (cylinder 4, 5 and 6)????
-
Any idea ladies and gents??
-
PS - Just reading the other post by someone on the AOS and decided to take the oil filler cap off during engine running, and it sounded very noisy, could hear something going on in there, like bellowing, you could literally hear the engine, not sure if that is normal and if not if the AOS broken would cause only one bank to mis fire?

Hi All, I have now had the fault codes from the memory, and glad I took your advice now, cause there were 8 of the little buggers!!! Ok here we go, P1119 - Oxygen sensor heater ahead of cat. conv., bank 2 P0150 - O2 Sensor ahead of cat. conv., bank 2 P1133 - Oxeygen Sensing adaption, lower load range, bank 2 P0300 Misfire detection (total) P0306 - Misfire, cylinder 6 P0304 - Misfire, Cylinder 4 P0305 - Misfire, Cylinder 5 P1130 - Oxygen sensing adaptation , idle range back 2 Just to help give the whole picture, current running condition, starts ok first time but smells very rich. ONce settled (warmed up) in to idle, it only idles arounf 500rpm and you can feel it misfiring, still smells very rich at this point. During driving, you can feel the misfires as you accelerate. The exhaust is black with sooty deposits. The car that took the faults off the memory for me said that he could not pin point the exact problem, and he doubted it would be all caused by an O2 sensor and needed it in to take a good look at it. Can you guys help with the disgnosis at all? Many thanks Russ
-
Hi Guys, Whats AOS stand for and can you point me in the right direction of the guide to replace this would this also cause the misfire maybe due to faild spark plugs from the oil? many many thanks Russ
-
ok, thanks Loren I cleaned the throttle body today, seems to be oil in the intake pipes, quite a bit too, is this normal?
-
haha....funny faces here we come!!! Could it also be the MAF and/or O2 sensors causing this.......or would they throw up a permenant engine light??
-
I agree, but with my day clear tomorrow, I was thinking on having a tinker myself first before paying out for Porchse to play. If anyone knows what could be causing this then I can take a look...........dirty MAF, loose coils, etc?? Cheers
