yea man i think you have a couple of problems there...

another thing you mentioned that AwwsChwA left out was the idle movement that could be your idle air controler

and for the code jumping are you using a scan tool or just jumping the wires...
cause if your using a scan tool it will tell you the codes and sometimes say no code found...
but if your jumping the wires i don't know what it would do...
are you jumping them right and what does it do if so...
