    Run, do not walk away from that car. We see this all the time: Deferred maintenance. If he did not care to maintain the car, what else did he ignore.........................
  2. JFP in PA
    Only way to know that is to connect a Porsche specific scan tool to the car and collect real time data.
  3. JFP in PA
    I am not aware of that happening.

    Welcome to RennTech P0335 and 0336 are cam and crankshaft position sensor issues, sensors are either out or wiring to them is questionable. P1266 is for your "drive by wire" system, which is also reading out of range, which can also be related to the sensor issues.

    Welcome to the world of 911 service. If you think yours is bad, take a look under a 996 turbo.................

    Most likely, you have burned out one or more circuits by doing this. I would test the alternator for output, but you have probably either smoked the voltage regulator or a diode or two, which will require replacement. The PSM is probably a ghost code due to the alternator issue. You may have also cooked other circuits that have not showed up yet, so be prepared.

    $36 a plug is more than a bit steep. Check the same part number on board sponsor Sunset Porsche's parts website, I'll bet it is significantly better..............
  8. JFP in PA
    Actually, it is pretty high based upon experience. I would pull the coils and look for small cracks, the give away sign that the coils are on their way out.
  9. JFP in PA
    You can read the alternator output with a digital multimeter, but the battery should be load tested.

    Scan them into your computer, then cut and paste them into the translator.

    Welcome to RennTech When posting questions like this, it is always useful to also provide the year and model of the car.

    That slight a tire pressure difference should not be enough to trigger this problem. More often than not, battery/charging system issues can trigger "ghost" ABS/PSM codes in these cars, so I would start by checking them first. I would also scan the car with a Porsche specific scan tool to see what faults are indicated.

    Welcome to RennTech Sunset Porsche is one of RennTech's board sponsors, and very highly regarded within the Porsche community at large. Many poster's here, as well as shops like mine use them almost exclusively for our parts needs without problem. Did you try to contact them to resolve your problem with them?
  14. JFP in PA
    No, the CPS would totally shut down the engine if it failed.
  15. JFP in PA
    OK,let’s start with the most obvious: Cracked coils are a problem, regardless of what plugs are used. They need to be replaced. As for the plugs, there are a wide variety of plugs that will work fine in these engines, ranging from the factory Beru to Denso Iridiums, but they need to be properly gapped. Most shops do not have the tools to reset the gaps on multiple side electrodes, so they just slap them in the way they come out of the box. Usually, the Beru’s are pretty close right out of the box and need no changes, which is one reason they are widely used.

    A photo would be useful, but it sounds like a line connection that requires a release tool.
  17. JFP in PA
    It is on the side of the transmission, under the car.
  18. JFP in PA
    That won't do it, it needs to be Porsche specific (PST II, PIWIS, Durametric System).
  19. JFP in PA
    The car is behaving as though the anti theft system thinks you are trying to steal it, and is shutting off the fuel and spark. You need to go back over your radio install and look for anything that would lead to this. Do you have access to a Porsche specific scan tool? It would be interesting to see if there is an open circuit somewhere in the security system.
  20. JFP in PA
    OK, let's try a long shot: When you replace the radio, did you ground the radio anti theft wire? The central locking control unit may be responding to what it thinks is someone trying to steal the radio or the car..............

    The only place I would use is Hoffman Automotive Machine, Inc. in Watkinsville GA.

    Not a good day. Intermix can come from either a cracked head or block casting, or a blown oil cooler. Pulling and testing the oil cooler is simple and quick, replacing or repairing the head(s) not so much. If it is the cooler, $200 for a new cooler, flush the cooling system a couple of times to clean it out, new coolant and you are back in business. If it is one or both of the heads, it is a bear of a job, and I would start by dropping the engine out to work on it on a stand (doing so is typically quicker than trying to do it in the car). If the head can be repaired, you are still going to pay $1-2K just to fix the head and go through them, which does not cover pulling or refitting the engine, just repair the heads, and there are only a couple of shops I would use for this type of repair. Good luck...............

    Year and model please................

    The Gibbs DT40 is an excellent street oil, high ZDDP levels, great film strength. We use it extensively in the shop.
  25. JFP in PA
    The final design IMS bearing tends to fail more on the track than on the street, unlike the earlier design's that did just the opposite, but they still fail with the same catastrophic outcome, albeit it not as large numbers as the first two design bearings. So while the third design IMS was better than the earlier versions, basically, any Porsche with an IMS bearing is at some level of failure risk, with only the level of probability varying, which is why the factory designed the IMS out of the engines in 2009. Cylinder liner scoring is not as widely recognized a problem, and there is little public data collection to point to a specific cause or level of failures. Most seem to point to two suspects: Cold weather and oil. All boxster design engine's can load the thrust side of the piston skirt on start up, and with excess fuel wash of the cylinders in the cold, combined with many modern oils no longer having useful ZDDP anti wear levels, liner wear can occur over time. Interestingly, other non boxster engines such as the Audi's also suffer similar cylinder scuffing, so it is not just limited to Porsche's.
