    Before you spend hundreds if not thousands of dollars on a clutch replacement, you may want to check out your clutch hydraulics first. They are easy to replace (relatively), and may fix the problem (see info on clutch hydraulic troubleshooting here: http://www.pelicanparts.com/techarticles/Boxster_Tech/45-TRANS-Clutch_Hydraulics/45-TRANS-Clutch_Hydraulics.htm . Usually, I have found that clutch pedal problems are not typically related to the actual clutch mechanism, but instead are related to problems with the pedals, and/or the master/slave cylinders. When a clutch fails, you will often find that the car slips in gear, or the clutch engages, and will not let out, or you will get through-out bearing noise. Sometimes a pressure plate that's on its way out will cause a "heavy pedal" but not that often. Hope this helps, Wayne Hi Wayne The problem is not a hydraulic with mine it's the Pressure plate, The fingers on the pressure plate has lost there tensile springiness... I have come across this before with other makes of cars.. I also spoken with the local Porsche specialist to me and he states this is common for the 986 Boxsters if they have done a lot of town / city driving through out the years... I got the parts for £212.09 all in (SACHS kit) then having fitted for £300 labor that includes VAT as well.. Thanks for all the reply's ! Rolfy

    To day was a beautiful sunny day here in the UK and as I've never really driven a Boxster I went a little 100+ mile drive today roof down and decent tunes on the radio "Car is sweet to drive" I really did enjoy it today... Could see my self keeping this one, well maybe for the summer!

    MAF fixed all running problems! Now runs perfect.

    Thanks for the reply! I will let you know the outcome ... Knowledge is power.. Rolfy UPDATE I have replaced the MAF, cleared all the codes and now is running like a dream! The MAF had caused all the drive-ability problems and Missfire codes.. Now having the clutch replaced has I have a "Heavy Pedal" I purchased the Boxster at Auction to sell on.. This will be in tiptop condition with a warranty once the clutch is replaced and also while I'm there I will be replacing the rear main seal as well "Not leaking but should replace while the clutch is out" as they are prone to leaking.. I'll keep you posted ... Rolfy

    Hi Wayne "Great write up" Had the Boxster checked out and they confirmed that the MAF is giving intermittent false readings BUT also said I may also have a problem with the fuel pump?? Recommends changing the MAF then re-test... I will post the results after the replacement.. Also spoken with another specialist today and was told that once you clear codes, it's common for the car to run rough if theres a problem due to all the adaption values being deleted... makes sense due to after I deleted my trouble codes thats when I had the drive ability problems straight away. what you think? thanks Rolfy

    OK New update: Engine is misfiring bad now! More than a MAF problem.. Yesterday I had cleared the codes, and took on a drive this morning and when cold it would hardly run.. Check Engine light flashed then stayed solid.. new set of codes! 1. P0300 Misfire Detection 2. P0306 Misfire Cylinder 6 3. 04889 P1319 Knock Sensor (KS1) circuit G6 1:Short to ground 4. 0488 P1318 Cylinder 14 Ignition Circuit Limit attained also found an invoice for the this car (I've just purchased the Boxster this last week) all 6 spark plugs and ignition coil packs were replaced on December 02 2008 but only 9,000 miles ago All my running problems started AFTER I cleared some codes (P1128 and P1130) with the Launch X431 Diagun... Only hooked it up to see if it works with a Porsche Boxster 986 Have I deleted some adaption values or ruined an ECU, I managed to drive it to a Porsche Specialist that is 5 miles away, Told him all the info he said that Porsche have been known to change the pin configuration in the DLC3 connectors and may have damaged something... If I had fried an ecu then I wouldn't be able to drive it would I? what's your thoughts? Thanks Rolfy

    ALSO mine is a UK spec car, will that make a difference? cheers Rolfy

    Yes I did. Sorry that I did not update on the post. It turned out it had nothing to do with the MAF. My AOS had blown and everything has been good after I had that replaced. Unfortunately I had to take it to a shop as reaching it while having the car on a jackstand was a quite a task and I gave up after an hour or so of struggling. The shop charged me $450 for labor which was pretty annoying. Which also brings me to an unrelated question to this post, are there places where one can rent a shop/lift/some tools by the hour and work on their own? THANKS for the update.. The Air Oil separator, is there a definitive way of diagnosing this as the cause of my lack of power and rough running? I did have a lot of smoke when it start up and started running rough? did clear away though, I do know thats a symptom of the AOS problem. mmm I think I'll start with the MAF clean tomorrow, have a visual inspection of the AOS and then go from there.. sounds like a plan? thanks again Rolfy

    Hi Did you ever resolve the problem, as I have the same P1128 and P1130 with poor engine performance? Thanks Rolfy
  12. RolfHarris
    Hi Guys OK this is the story, purchased this car with 104,000 miles on it ... It's in very good condition and has had every service. has been running great until about 2hrs ago. I thought I would see if my Launch X431 Diagun could read / stream live engine data. I first go in to engine codes section, click on fault codes and to my surprise I see 2 (I have not had the CEL on when driving does light up when ignition is cycled) 1. P1128 Oxygen Sensing adaption idle range Bank 1 2. P1130 Oxygen Sensing adaption idle range Bank 2 So I cleared the codes, started the car, ran rough when 1st started, then the idle settled down BUT major lack of power, feels as a misfire flat spots through out the whole rev range. Drove to BP station about 3 miles filled up with 98 Premium fuel as I was low. Drove back was a little better but still lack of power. I have done a forum search and what I can gather is the MAF is a possible candidate. Now this car has driven for 90 miles fine then I clear some codes and now this? Coincidence? what you think? I'll clean the MAF tomorrow and see what we get? Also can you let me know what the readings for the MAF voltage should be when at Idle and say 2200 RPM? I've experienced bad MAF's before and this does feel the same? Cheers Rolfy
