[DSMITCH104]

Noticed sometimes , when im shifting my rpms drop all the way and dash lights come on for a split second. like it wants to die, but never does. Drops down and then bounces back as normal ? maybe my idle is to low on my dsm link v2 ? thats prob not it Im getting my lab top this week so i can start getting used to dsm link.
Anyone is socal have a deal on a wideband?
Any help would be appreciated, ive searched and searched

the power to your fuse box needs to be tightened on your battery most likely. seems to be common. or tighten your negative wire as well.

Is thier a post i can check under the fuse box for the power?
