so those of you who follow me on facepalm will now know that the Porsche is back on the ground after nearly two months of me putzing around with the cooling and PCV systems on the poor beast. As of last weekend the car was on the ground and driving. It is not fixed back to 100% but I did drive it to work on Friday as a mini victory dance!
So what remains? I am not completely certain but while running the engine to fill the coolant I did notice that it was breaking up pretty bad at no load high RPM areas. This leads me to believe one of two things:
1) fuel injectors are clogged, dirty, or otherwise not up to par.
2) coil packs are failing, but not enough to set off the light.
I am still getting the max lean-out code via the OBD, which would agree with either of the above eventualities.
I think the first step is to locate an affordable set of coil packs and replace the missing coil pack heat/debris shields. My experience at work with heat soaking vehicles has made me a firm believer in the use of these shields when the coils are so ridiculously close to the exhaust system. The point seems to be highly debated on my online porsche forums about whether to leave the shields in place or remove them to not "hold heat in" and I can tell you with a high degree of certainty that the amount of heat kept out by those shields highly outweighs the amount of heat "held in" by them. just my two cents.
anyway, the search is on for said coil packs, and also in the peripherals have cleaning the injectors on the list.
The porsche 996 injectors are also strangely specific, compared to my experience with BMW injectors. the 12ohm resistance is not impossible to find by not overly typical.
Also the $292/per injector that Pelican parts wants is the most rediculous thing I have seen all day! When you can get one injector cleaned for $20 I don't understand why you would dish out 15x that amount for a new one!? sheesh!
