slow car-how to test cis-e/ignition?



It could be possible for it to be the knock sensor, but I doubt it.  Cheap fix anyway, though ($40).  I'd try the knock box/ICM swap first (my money's on the ICM), and if there's still a problem, *please* try swapping plug wires... I know it sounds strange, but my *NEW* wires were the bane of my car's existence for the longest time.  Ran like poopy with wheels.  Only didn't smell as bad.
