ui, I have bunch of problems with my sl55 04. It has only 34k. Loss of power when I floor the pedal. From reeding posts its a travel speed censor. So I want to change the gas pedal. I already got the part but need step by step instructions how to do it.

ABC flashing red for 3 seconds when go over bumps.
Trunk & doors soft close , massage seats does not work.
I changed the trunk latch. It was licking air all over the place. Now the trunk will pop open but wont lift up.

I also want to chane aux pump which I already got but also need step by step instructions how to do it.

If anyone knows how to fix it or have any advise, please let me know.
