Over the last month and after I had the car services at an Indy I started getting random P0300/PO301/302/303 and the engine when that happens it does not sound happy. The error only last seconds and a lot less than a minute and then disappears. By the way the car is 997 2006 with 51k on the clock and had it for over a decade now
As I dont drive the car that much and only goes out of the garage a couple of times a week it has not affected me that much but I am scratching my head trying to find out what might be. Worth noting that I also notice that it only does it during start up when completely cold and after not using it for 4-5 days. During the day if I use it then park it for 2-3h and use it again its fine and does not give any problems.
My suspicion after reading a number of threads and advice from deMort is that the Solenoid/Actuator Valve get stack when cold and it cause this problem. Based on the codes I assume is the one near side of the car. I jack it up today and had a look after I remove RNS wheel and although the space is tight I can reach and unscrew the heat shield that gives me access to the Solenoid Valve. I didnt continue further as I was not sure how complex/difficult will be the next step and also didnt have a spare which from what I have seen is about £100 to buy (99710530100)
So a couple of questions #deMort or any other resident mechanic
1. Do you agree with diagnosis ?
2. How much a specialist would charge for replacing it if I dont find time to do it myself ?
3. If I do it myself how long should it take ? What are the risks ? The workshop manual that I have doesn't indicates that is complex although it gives the usual warnings etc
4. Anything else ??? Advice ?
Thanks in advance
ps: I have not posted for sometime but still around
