  1. Ped,

    I had this experience before with my 97. I did ignore til one day, the light start flashing and then smoke comes out on the air vent. All the coolant were scattered all over. It turns out the water pump failed. You might want to check your water pump and make sure it is not leaking coolant when the engine is running. To access to this you need to remove the carpet between the seat and the cover. This is the area where you want to change your belt.

    Hope this help.


  2. Just want to complete this thread in case someone who might run into this problem in the future, here are what I did to fix the problem (at least for now):

    -After reset the codes and keep on debuging the issue.

    -I got the new famous error codes (P1128, P1130), all the previous codes were gone except these two.

    -I clean the throttle body, replace the new oil filler cap

    -Installed a new MAF sensor

    So far it had been at least 5 cycles of driving and the CEL light has not come back (keep my fingers cross).

    I noticed before when I reset the CEL, the CEL light came back after driving cycle #2 or # 3.

    For now, the car runs very smooth and will keep an eye on the CEL :D

    Hope this info will help others who run into the same problem as I did.



  3. Todd,

    This is great post :clapping: . I have a 97 and thinking about the upgrade. However, I don't have "PSM" (porsche stability management) or traction control as an option of my97.

    My concern is all the extra ponies on the upgrade on a car that does not have "PSM" can be a scary experience :jump: .

    I am just wondering if you boxster has the "PSM" added to handle the power.



  4. All 300 series faults are misfires that can damage the catalytic convertor. P0300 is multiple misfires and P0304 would be cylinder 4, P0305 would be cylinder 5 etc.

    P1316, P1317, P1318, 1319 are also misfire detection emissions relevant. Again these refer to cylinders 4, 5 and 6.

    P0150 Oxygen Sensor Ahead of Catalytic Converter (Cylinders 4 - 6) - Intercore Short Circuit or Limited Voltage Increase. 

    So the problem you fixed was on the 4,5,6 engine bank side?

    If it was then you likely got the problems. Now you will need to wait and see if the light comes on again.

    Thanks Loren.

    The CEL comes on again. This time it is fashing.

    I had search the web and found some old post from the www.ppbb.com.

    It inidcates the problem can be timing issue on Vario cam, solennoid tensioner or blown enginne.

    When I change the oil, the old oil was clean no indication of mixture of oil/coolant.

    Do you have a picture of the solenoid? I might want to replace this and see if it is the culprit.



  5. Loren or Jeff,

    Do you guys know what these codes really mean? I took the car for a drive today and the CEL comes up again.

    From my ODBII readers:

    The trouble codes= P300, P304, P305, P306

    The pending codes= P1316, P1317, P1318, 1319 and new code P0150

    On Sunday, after fixing the contacts of the plugs and air leak on the throttle, I reset the CEL and took the car for a spin, the CEL did not appear.

    This experience has been a roller coaster ride for me

    Man, I wish I were at the tech session at RMG last time :(

    Thanks in advance,



  6. The local dealer has 3 of them.  I already talked to them about buying one, since they have several PIWIS testers.  They are going to keeep the older PST2 testers.

    I do not think you can buy a used PST2 anymore since it has been replaced by the PIWIS.  You can buy a refurbished PST2 but it is very expensive without an exchange unit.

    There might be an alternative.  Stay tuned.

    Thanks for the info, Jeff.


  7. For the DIY folks, we sometime might need to use the PST2 system to detect/adjust the car system or disable the Air bag light ..ect. If you notice, the ODBII code reader capabilities are very limited.

    Yet, the system is expensive, but if we all chip-in and share the cost. It will be better.

    So what do you all think? Is this a good idea or not?



  8. The problems solved:

    First I want to say "THANKS" :clapping: to Loren for helping me to track down what the codes were, they were very helpful.

    Here are what I found:

    - A leak in the air intake.

    - Connection to the plugs were not plug-in correctly.

    - Need new fuel filter

    - The platinum plus 4 are not good for the boxster.

    It always, good to put a bottle of techron into the gas tank to clean out the injectors and valves.



  9. Ok the saga continues :-),

    I purchased new fuel filter and new set of spark plug (NGK with copper 2 electrododes) to give this a try.

    Put in new plugs and new air filter and fuel filter plus getting a nasty cut on my finger :-(.

    Since, I already had the car at the service position, I gave it a new oil/oil filter change.

    Now, I clear out the codes and start turn on the key. Guess what, the CEL is blinking and then stay on.

    Plug in the code reader and there you go: P0300, P0306, P0304 ....P0305 plus the old code P1316-P1319.

    Anybody, has any idea? look like I may need to contact Tim at Porsche Fast Lane for a 3.4 up grade :-).

    Ok, I will call it a day (work on car for me).

    If anybody has any suggestion, I will appreciate it.


  10. I replaced the spark plugs when the car was @ 65K miles now it is 81K miles.  I used the platinum plus 4 plugs.  Don't know if these  plugs are the cultprits since there was a discussion about it.




    Do you have the part number for the plugs? So we can figure out if they are the wrong heat range or profile.

    I went to the site (don't want to tell the name here :-) ) and looked for the part #, guess what.... they don't carry it any more.

    Look through my record and found it, here is the info:

    Parts Ordered

    Porsche 1997 Bosch Spark Plug Platinum+4

    Qty: 6

    Part #: F1000-61923

    Interestingly enough, I also ordered 18 plugs (+4) for my mercedes at the same time. Now my mercedes is also acting a bit strange lately. I will order the new sets of plugs and replace them this weekend. I will let you know if this is the problem.



    P.S Jeff, I was planning to attend the tech session but things came up and I got stuck :-)

  11. Hi Loren,

    I fixed the temperature sensor and clear the code. Now the CEL comes back and I am getting these new codes:

    P1315 Misfire, Cylinder 3, Emission Relevant

    P1316 Misfire, Cylinder 4, Emission Relevant

    P1317 Misfire, Cylinder 5, Emission Relevant

    P1318 Misfire, Cylinder 6, Emission Relevant

    P1319 Misfire, Emission Relevant

    Do you know, what can be the culprit for these codes? I did check my gas/oil caps.



  12. Hi guys,

    It is now my turn to get the CEL :D . I plugged in the scanner and got these codes P1130 and P0117.

    I have been reading the forum and noticed the P1130 can be the MAF and the P0117 has to do with the coolant temp sensor.

    If anybody has any input based on the experience, I would appreciate it.

    Thanks in advance,


  13. Congratulation on your purchase.

    Well, mine is a 97 and it has 80K miles plus. I think 150k mile plus is reachable or even more if you are maintaining the car properly.

    As far as minimal work, the boxster is considered to be the one comparing to the other models.

    Just enjoy the ride :-)


  14. Based on my experience, the water pump is the culprit.

    you need to check the water pump. There should be some coolant leaks.

    It might drop on the serentine belt.

    If you keep driving without fixing it, eventually,

    the amount of coolant leak will increase. As a result,

    you will see alot of smoke coming out from your engine (coolant leaking).

    Hope that is help :D
