Your tps voltage is at the bare minimum at idle, your MAP is low, and your knock should be 0. I think the MAP is supposed to be close to two.

Well just those numbers by themselves don't tell you much other than the tps is set correctly if you were at idle. You need to look at the whole picture. Knock counts are counts of knock in milliseconds. 1 millisecond could have been you closing your door, don't worry bout it. I get 10 when I shift just becuase my tranny shifts hard. When and where knock counts matter more than how many. If that is map voltage then it could be ok. Most cars idle with 30-50 kpa. I couldn't tell you what that is in volts. You need to drive your car around and see what it's doin. If auto x-ray doesn't log data for you to look at your got ripped. winaldl is free and logs date and does all kinds of cool things.
