97' S70 Random Stalling

Hi guys! Thanks for the quick response.
Just a quick update, I got my Fuel pump relay and ignition switch in the mail today.

Got them replaced and the car still would start! so, I went ahead and checked the battery leads (terminal) and noticed that the positive terminal was loose to the point where it can be twisted around even though I've tighten the nut all the way.

So I tried to wiggle and sit the terminal properly and boom the car just starts. Went for a quick test drive and everything seems fine. Not sure if that is the main issue but tomorrow, I'll be taking the car in to get the terminals replaced.

I'm hoping to use the car more once the terminals replace to see if the random stalling still occur and keep this topic updated!

Also for the cluster bulb not working in posII as mentioned by user (Misha), it was like that when the car failed to start.
I've added another video to show the clusters at each position, can someone confirm with me again if there's still something wrong with the cluster at posII?

Still no CEL on pos.II.
Because the cluster is like that when car refuse to start is pointing towards bad ignition switch.

Battery terminals MUST be real tight or you are risking to fry some modules and alternator.

After replacing the ignition switch and sitting the battery terminals i manage to get the car starting just fine.

as for the cluster warning light should they all be lighted up at posII? also is it possible that its just a blown bulb?

They must...it's so called...bulb check on pos.II.

It could be blown....Vol-Fcr is needed to scan the cluster or ecu for codes....or simply to pull the cluster out and to be checked.

hi guys, another update.
Stalling issue seems to be gone after ignition switch replacement (done about 50km on the car since). Gonna have to drive the car more this coming week. As for the cluster, it's gonna have to wait till this upcoming weekend.

Anyways thanks for the suggestion everyone I will keep this post updated as time goes by.
Really appreciate all the feedback.
