01 s80 etm issue

[Oldsguy]

Been havin issues with throttle module. Replaced orig with a rebuild and 2 new modules thru dealer. Car is still acting up and wont show codes. Surges, and stalls..then seems to run fine. They cannot figure it out and they have been driving with scanners attatched for 2 weeks now....any one have ideas? Then outta the blue sunroof quits..open of course.

the sunroof issue could be associated with the security system module
sometimes "waking it up" will fix it

search this site for remedies
this is where I found the fix
