I have had trouble with rough running. I checked the codes and got a code 7 on pin 8 that is knock output in EAL/AKR to CFI faulty. What do i look for? Woukd it be the wiring? I am unfamiliar withthis setup!

I can tell you that it happened suddenly and the vacuum (MPG) on the cluster is pegged to the left! Also it hardly starts and will not come off idle until it warms a bit tnd then there is a hesitation. Actl like timing is retarded.

thx
