I replaced my OEM shifter with a short shift kit a number of years ago. Shifting is has gotten extremely sloppy now and suspect my bushings are completely worn. I see online there are a large variety of materials used in replacement bushings. I would presume my coupler is fine and I only need to replace the bushings there as well. Do you have any recommendations as far as the type of bushings I should consider? Thanks, Jeffrey ...

READ ANSWERWhy 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.

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 removed it and disassembled it to find a break in one of the wires. I repaired the wire, have good continuity and rebuilt the WUR. 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 ...

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 ...
