The first step in repairing your issues is to know what codes you have so we can see what's going on.. Can you post the codes that are in the PCM-ECM-DCU modules?

Talk soon,

As soon as I get the codes I will be able to tell you how to fix it, but without the codes it's anyone guess as to what is wrong..

Standing by.......
