[s-cars] Bucking 95 S6

[RCaro900SS at aol.com]

I posted about this problem before. The car will start to buck at WOT at  
approximately 3000 RPM & again at approximately 5000 RPM. I  pressure  checked 
the wastegate diaphram & substituted another working MAF, and there  was no 
change. I finally bought the Ross-Tech VagCom. There was one fault code,  00513 - 
Engine Speed Sensor (G28) 27-10 - Implausible Signal - Intermittent. I  
replaced the sensor and the problem still persists. I am still getting the same  
fault code. Any thoughts out there?
 
Thanks,
 
Robert
