Last year, when this happened the first time, the oil was in fact Mobil 1 15W50.
BufordTJustice - Liqui Moly 5W40 is A40 approved oil, about 2K miles on the oil in the crankcase. I did replace the spring and valve 20K miles ago during my DIY top-end rebuild.
Loren - the car is 2000, 996, convertible, with ~197K miles, underwent a DIY top-end rebuild 20K miles ago.
Need some help. Yesterday Tucson was about 108 in the shade. After driving around and engine temp high but within operating range, the engine started to hesitate. Applying some gas, brings the idle back up but if I release the gas RPM goes low and threatens to stall. Conditions: A/C on (did I say it was 108 deg in the shade?), at 3000RPMs oil pressure is at about 2 bars, at idle 750RPM oil pressure goes about .6 bar. Going to work that morning (88 deg outside) all was well. Last year in August, same thing happened, I had attributed it to having just replaced the oil with Mobil 15W50 that morning and the incident happened that afternoon. I immediately replaced the oil back to Mobil 1 0W40 the next day and no incident since. This April, I replaced the oil with 5W40 Liqui Moly and have not had any problems until yesterday. No other things have been done to the car that stands out being unique from the time this happened last summer. I am getting ready to go back to Mobil 1 0W40 but I am at a loss as to why the oil viscosity might be causing this....or maybe it is something else like the MAF. Any thoughts out there?

Thanks for the tip (pun intended)! I did the same epoxy job. Works great.
So I just had one of the tips on my 2000 cab fly off last night. Really.....I have to replace the whole nozzle for $193. No replacement tips?????
RRRUFF replied to Stakeman's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Thanks for the post. Other than the LN install kit and the Clutch alignment tool can you share your list of parts and tools with the rest of us? BTW what was your final tally on actual hands-on time?
Congratulation on your 996. Sounds like you have the problem taken care of. I am glad to hear that you were able to take care of the problem. I too purchase my car in CA (San Diego) and drove 500 miles to Arizona. Loved every minute of the drive back with my 12yr old son beside me! Smiles the whole way! I plan on doing much of any work on my car as well so I like seeing posts like these and I plan on doing it myself as I go.
