2003, 6 years, 139,000 miles...never had an issue with the engine or performance. Regular maintenance. Best car I've ever owned... Bill B) Must admit, the fun and exhileration of driving a Porsche far outweighs the cost of maintenance...even though I have spent a good £2000 in teh past 12 months, for 93K on the clock, not too bad...absolutely love it! BTW, Porsche say do not rev above 5000 or may cause engine problems...
Yes, right sensor was changed...lost code P1126 (if I remember code right?!)...P0134 only code i get...well, will either be wiring harness (nothing dodgy apparent) or DME then..sigh...any money its the DME! Never straight forward this...any checks I can do that do not require much messing about?
I had the 02 sensor replaced and the ECU is still throwing out this code: P0134 - 02 sensor - interruption of signal Would this be due to the MAF being unplugged at present? That's what i am thinking...
Check these out for some ideas... http://uk.youtube.com/watch?v=zv_ljlNOe7M http://uk.youtube.com/watch?v=KzEcEUt_aB8 Really it is the last part of exhaust for sound...high flow manifolds/headers allow more gases to escape the engine quicker allowing new air in...therefore, more HP...I fitted high flow manifolds and now get a deeper sound...???
Exhaust manifolds...needed replacing so upgraded to high-flow stainless steel... Thought MAF was new style, turns out was old style... All the work I have had done has been maintenance...would also like alloy wheels refurbished (look knackered!) and am having new 02 sensor installed (again needed as one of mine is duff)...MOT due in April...also have air filter en route...
This IS my second MAF sensor from Sunset. I sent the first one back and am still out $$$ till Bosch refunds Sunset. BTW: I did see 2 spots and only for one brief spot at 2 very different time slots where the Hot Film MAF went to zero. Idle values of the Hot Film MAF seem kinda high (24-37 range at 600-800 RPM). Hot Film MAF is seen in the 200 range at less then 3000 RPM. I've no comparison data so I don't now if this is normal. I was up pretty late last night messing with this to no avail. Unplugged the MAF and there the car sits for yet another day... How frustrating!! I take it your 02 sensors work perfectly? I think by now I would be seriously considering letting Porsche run a diagnostic and see what they think...
I have found that connecting the MAF, a new one, the car had problems with idle, acceleration...was due to a faulty 02 sensor so both cause an issue if one not working...disconnecting the MAF ironed out the problem...am having new 02 sensor fitted Tuesday What were the codes? Only today will I have time to get to this. Based on the graph I posted, I would think it to be more wire/connector related due to the rapid drops in voltage or MAF values seen. I don't want to event think about the DME. That and the whole engine wire harness are over $1K each. I am hoping to find an exposed wire rubbing against the car body or simply a bad connection at the MAF sensor itself. If not, I will disconnect the DME harness at the DME and reconnect. Did not seem easy when I was looking into that area last week. I'll also clean the MAF Sensor connector (connections) as well. I had codes P0134 and P1126 all to do with the 02 sensor in Bank 1 (right hand side of car)...only codes I had...

Um, no access to PST2...I guess the old style is right then?! Starting to make sense now; although, new style sensor was removed...perhaps someone fitted the wrong part for the car??? Hmmm... O2 sensor arrived today, so, will fit and see what happens...right side of car, ok...let's see Thank you...
I plugged in my new code reader today and was presented with the following codes: P0134 - Oxygen sensor ahead of TWC, bank 1 P1126 - Oxygen sensing adaptation, lower load range, bank 1 Reader said: Fault: 00 Pend: 02 I am guessing this is a lambda sensor...??? I had to unplug my MAF as was causing idle and acceleration problems...unplugged, problem ceased..! Any ideas would be gratefully received...many thanks
Six (6) new tires...I'm assuming two sets in the rear and one set in the front? How miles did you put on the vehicle over the past year? I've got an '03 (non S) with 138,400 and other than the bulbs and regular maintenance, I haven't had to do anything. I'm still running hard on the original clutch. I drive a mountain pass each day and drive hard...my tires have been pretty good too. ;) Best car I've ever owned. All the best, Bill B) Yes, was 1 set for front and 2 for rear...the S really rockets and i guess I drive too hard! lol I have done about 10000 miles in past 12 months...
