1990 740 Turbo - 191,000 miles -
She starts and can be driven. Have code 224 on socket 6. Have the idle where it is suppose to be after cleaning throttle body. I have replaced crankshft positioning sensor, coil, wires, cap and rotor, plugs, throttle positioning sensor and igniter (the device on the left fire wall with a heat sink) - When idling, there is an occasional cutout and the car will not accellerate without cutting out a little. It will accellerate but not how it should. Seems to be runniong rich. I cannot find any vacuum leaks. I have replaced nearly all rubber lines. The 2-2-4 code is the only error code. socket 2 is 1-1-1. The check engine light is not on. The car does not start up immediatly but turns over a few times. Comprssion is good and when the car was running better a couple months ago, it had lots of power. Seems it just needs a little tweeking to bring her back to her former glory...
