does anyone know where to get any information for the 117 AMG engine shown below? it is basically a high output 117 V-8. i saw the pictures here on the forum years ago, and am actually working on the same car at my new job in costa mesa, the engine was just rebuilt for 23k, it starts and runs, but seems to have some control issues. has a surging idle, the one thing i have found were steel injectors, after replacing them it runs alot better and does not miss. but still has the surge, when i disconnect the computer the engine still surges. i found today that the mount for the crank sensor had been modified, to the point that the sensor it's self had to be shimmed so it wouldn't hit the flywheel, i am sure the air gap between the sensor and the flywheel may be off, does any one know how critical this is? or what the gap may be? the car is a 300CE modified for this engine, when i run the vin, it was originally fitted with a 104 engine. any info appreciated
