Well Mike I didn't have to do any work on the Modulator just replaced a bad SVS. The codes I was getting were because of a bad connection at the modulator and because I had not driven the wheel sensors home when I cleaned them,,,, I re-seated the sensors and replace the small plug at the rear of the modulator... not more issues...

It's taken me a month and some heavy learning curves, but I have managed to re-build the heads and fix a number of small issues; causing a light show on the dash... but all is done now..
