My LHS 3.5 litre check engine lite is on when checking the code it comes up with a code #66. Have replaced the in dash circuit board already problem still there. the vechicle shifts into limp mode and all guages stop working.The guages turn back on and limp mode is then off. have been told that problem could be key switch or one of the computer moduals need help.
