Why does my 944 Turbo hesitate and sputter during first 5 mins of driving?

Saturday 11/15/2025 | 1986 | 944 Turbo | Engine

Every time I drive my 951, the rpm’s will drop very low and when I give it gas the car will hesitate and sputter. This happens within the first 5 minutes of driving and lasts for 30 seconds to a minute before the car accelerates normally. After it happens the car drives perfectly fine with no issues.

Why I am I experiencing a total electrical power loss after trying to start vehicle?

Tuesday 11/11/2025 | 1982 | 911 SC | Electrical

Hi. I have a 1976 911 s (with a 1982 sc 3.0 engine). I am in the process of sorting out a rough running engine. I discovered that the WUR had no continuity.

I put it back in the car, turned the ignition to on and lifted the air sensor plate to circulate fuel. I attempted to start the engine, heard a very brief "turning over" and then nothing (like I had blo ...

My 1972 911T was outfitted with virtually no options. Only tinted glass and stabilizer bars. I would like to change to full gauges rather than idiot lights. If I change the dash, would I have to change the sending units (oil pressure, etc.) as well?

Tracking a stock Carrera

Monday 11/10/2025 | 2006 | 911 Carrera | Engine

I will try to make this simple. I have years of track experience with another German brand, a instructors license and a racing license from them. I bought my first 911 6 years ago and daily drive the car. I tracked the car a few times after buying. I was told though that really the only 911's that should be tracked are the GT3's , GT3 RS, and GTS in the 911 cars. That my stock Carrera really wasn't made for that stress and would fail is pushed too many times. I have since not tracked the car ...

Casey thank you for the quick response answering my question about the black foam pieces coming through the vents. My question is would you happen to know if there is only one flap to recover with the foam tape or are there two individual flaps. On the videos I watch they are only concerned with the one flap that you see through the heater core box.
