thanks ICE but I know what the code states just not what causes it or how to fix.

Reset and see if they pop back, if yes good chance your EML's are bad

What year?

[SHEBUILT]

1998 and I did the reset and nada. Even had it flashed as you suggested a while back Edwin

it may be time to get inpa on it and read each module individually... you get more detail that way...
