One code is for IDM ign monitor.
2 codes are engine tempt and air intake sensor or circuit high which spells low temperature.
And one is idle control problem.

But code do not say replace stuff but check it out.
How is it running?
Is engine coming up to proper tempt?
First I would clear codes and see what comes back?

Post back what comes back.

well i have a reader but it won't clear the codes for somereason, The Engine runs good/smooth, comes up to temp like it should, the previous owner stated he had the engine rebuilt and i get a feeling some stuff wasn't hooked up correctly, i havn't dug in to the engine electrical deeply yet but what i have seen so far there are a lot of BAD electrical connections (I.E. twist n tape) after i get some coffee in me, i'll dig in deeper and see with what i can come up with.

MT i did try to clear the codes, and the reader i am using wouldn't clear them, using this reader http://www.iequus.com/Product/Detail/781BD308-1646-44D7-8B5A-AA8D790E6DA4
and all i got was ERROR, i even went as far as unhooking the battery terminals and try to re read.

Clear codes first to keep you from working on false problems.
A scanner may be needed for clearing codes.
Auto Zone or your parts place might clear codes for you.
Let us know how it goes.

You need a OBD11 scanner or engine capable scanner to clear codes.
Battery disconnect or code readers will not do the job.
