Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

1 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

  • Planet-9: 1 discussions

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1Original post

Hello everibody, I own a Boxster 987 3.2 280 hp my05 since 2009 with 59k miles; my car has always had unstable performance and a little poor hot start, but i didn't mind it beacuse Piwis checks were allright. I've always used Mobil 1 5w50 changed every 6000 miles....oil consumption is normal about 0.6-0.7 liter every 6000 miles; No track and a very nice use. Last year I decided to restore this engine in a Porsche workshop changing many parts including: -Spark plugs -Ignition coils -Mass air Flow sensor -Fuel pump -Fuel pressure regulator -Relays Fuel pump and Dme -Vos -Water temp sensor -Engine compartment temp sensor -Ultrasonic injectors cleaning -Tank cleaning -All oil vapors tubes -Coolant -Water/Oil exchanger -Air filter -Crankshaft pulley belt -Throttle body After the injector cleaning hot starts are worse; essentially after 20 -30 min i stop the car, when i try to restart engine employs 4-5 seconds to start and sometimes I see white/light blue smoke that smells of oil burned. Then if i stop it and try to restart, there isn't any problem. The same day after the injector cleaning i broke a secondary lambda sensor after cat (right bank code P0159), so i changed this sensor too. All parts i've changed are genuine Porsche . However performances are unstable and engine is rough too. We have done many Piwis tests inclunding lambda sensors and variocam tests but it's always allright wiothout any fault code. Compression cylinder test is ok and there isn't any air aspiration; starter engine is ok, Evap canister allright too. Porsche workshop has no words. Now i've bought 6 new injectors from Pelican Parts and I'll try to replace them. I've spent so much money and i don't know what to do!!! If you can give me some advices, I'll be very grateful. I love my car too much and i want absolutely solve this problem !!! Best regards Alessandro
