  1. Hi All I was fairly sure that my erratic idling on my 2000 model Boxster S - never less than 1100 r/min and often shooting up intermittently to 2000 r/min - was caused by a dirty throttle body or MAF sensor. After cleaning the TB it made no difference and having caused an air leak on one of the rubber sleeves where it attaches to the plenum, I decided to give the job to my local specialist. The problem was resolved by repairing a hole in the brake vacuum hose, caused by the hose chaffing against the bodywork. I suppose that with 19 years under its belt and 147000 km I could exp
  2. Hello, I'm new on this forum and stumbled upon a new problem (or old) with my 2.5l 986 Boxster from 1997. The problem occurs when the engine is started dead cold after sitting a few hours/overnight. Engine starts immediately but the RPMs start to surge / hunt between 1100 and 700 RPM. This continues for about 10 seconds after which the idle smoothes out to the normal cold idle RPM. The first pull away requires a tad more throttle then normal to prevent stalling. After this first pull, everything is almost normal and engine performance becomes better and bet
  3. My 1998 Boxster suddenly had hot start issues where if left in the sun here in Texas for a few hours would then crank but not fire unless you kept cranking and pressed the throttle. No issues when starting cold. It had thrown some evap leak codes a few times and a secondary AI once but nothing consistent and would also suffer from idle issues if hot start was hard. Having read many threads I decided that it was not fuel pressure related as in my experience fuel pumps either work or they do not and the same applies to the associated relay. I read someone blocked off the
  4. Hi guys, I’m writing from Italy, owner of a 2000 986 S, 84.000 km on the clock. First of all, I have to apologize for my poor English. Recently I had my cluster bulbs replaced thanks to the good DIY guides found over here, so, thank you so much for helping us all with your knowledge and patience. In order to do the job, since my car features the optional alarm, I previously disconnected the negative cable of the battery while leaving the ignition key on position 2 as read on the board in order to avoid the siren to scream (is this correct, BTW?). With the cluster back in place, witho
  5. Hi I just bought a cayenne 3.2 V6 2006 base model, on my way home car was running fine, second day morning went to put some gas and after getting home car idle was rough Stop the engine and start back on now the car start goes to 1000 rpm for 5 seconds and then start shaking going to 500 rpm or less for about 30 seconds then car it self try to correct and goes to 1100 rpm for the same 5 seconds and then back to the bad idle. If i press de gas pedal right after the start car goes fine without any issue to 4000 rpm for the same 5 seconds and then complete loose the power, back to the
  6. H! I have an 996 - 99mod manual 3,4L. When i start up it seems like it misfires. It`s kind of a knocking sound. Sometimes it stops on idle. When i push the throttle for a ouple of seconds, it smokes a lot and then the knocking goes away. After that, I let it Idle - but it slowly rises from 800rpm to around 2000rpm, then it drops to 800rpm again and do the same thing over and over again, Does anybody have a clue? This is the fault codes i found: P1601 -CAN timeout - instrument cluster P0600 - CAN timeout Tiptronic
  7. 2007 C4S with Tip and 58,000 miles My CEL came on yesterday, due to codes 2187/2189. After a brief search on the internet, loose oil/gas caps came up as possible causes. So I cleared the codes and tightened the caps, but the CEL came back a few hours later. I also just noticed last night that, when idling in Park, it revs at ~1,100. In Drive with the break on and the car not moving (no pressure on the gas pedal) the idle revs drop to normal (around 700-800). Also the idle is a little rough. Any ideas what causes this? Thank you all.
  8. Hello everybody, recently has the engine of my Cayenne V6 ( Bj. 2004) sounds like a diesel. The sound is subjectively from the left side of engine ( in direction of travel). Coupled to the noise is uneven running in the state . The error occurred suddenly and without warning after I turned off the engine and about 2 minutes later started again. I have read the following Durametric 2015_03_14_12_55_03_Cayenne Logfile.pdferror codes: P0016 Position camshaft to the crankshaft Bank 1 - Upper limit value exceeded , test conditions are not- completed , fault is currently active and is not C
  9. Need everyones thought on this one. My04 S. Over time my idle rpm starts to drop and pulse when stopped. eventually it will throw a PSM and using Durametric I have P2186 Throttle body sensor. I cleaned the throttle body, cleared the codes and she purrs like a kitten. Slowly day after day she will start to drop rpm coming to stop and start the whole cycle again. it takes 3 to 4 weeks. I have checked throttle body, coils, plugs, fuel rail. I don't know what else to check?
  10. New to Porsche and this website. Just bought a pre-owned 2002 911 C4S with only 21k miles. New RMS and IMS bearing. However, idle is rough. Is this normal?
  11. Hello everyone. I've had these two faults appear three separate times now, all within about 100 miles of each other, and all when the car has been idling for a short period. P0172: System too Rich (Bank 1) P0175: System too Rich (Bank 2) I've searched the forums, and it seems the likely cause is the MAF, but I wanted to post my Torque Pro logs of when the CEL occurred to see if any of you could help me pinpoint the problem. For what it's worth, I just changed my spark plugs last weekend (after having seen the CEL twice) and inspected the ignition coils, but no problems were found and t
