codes

i have a few codes that came up when i did the check engine code retreivial and i have a chiltons manual but dont really tell me what the cause of the problem. here are the codes - 13 no change in map from start to run
15 no vehicle speed signal
24 throttle position sensor (high or low) voltage
36 waste gate soleniod circuit
45 turbo boost limit exceeded
51 o2 sensor says lean
61 baro read soleniod circuit

now do i have replace all these items? bought car for 400.00 and found rocker arm laying head and vacuum lines cooked. replaced tees and lines that were melted and now it runs on all 4 but when you start to get boost it falls flat but stays running. does dodge sell a complete vacuum line with restricters and all or do i have to scratch my head and guess on the right parts needed? any help would be thankful.

I found out that dodge doesnt sell vacuum line set so now its of to the junk yard. found out that the turbo isnt creating any vacuum so i tied the waste gate to manifold pressure and now the turbo works with out falling on its face, i do have a grainger valve parts on the why to make one. whating on insurance card before putting on the road for the true test. still if any ideas to help on any others things that might need attention dont hesatate to reply. thanks.:help: :help: :cyclops:

Some of those things you might have to replace and some you might not. The best thing you can do is take it to the dealership and have them hook up their computer to it and they can tell you what all the codes mean and what you will have to do to fix them. They will probably charge you about $60.00 to do that, but if you can do all the stuff yourself it will save you time and money.
