Default 2004 Verona stalling...ECU reprogrammed 2005...is it bad again?

Hello all, new member Sam here.

I've searched the forum quite a lot for answers but found I still have questions. Hope someone can help.

My mother's 2004 Verona is intermittently stalling. Two coil packs were replaced a few weeks ago, along with all 6 plugs. The center electrodes were worn down to the diameter of a sewing needle! I read this can cause the coil packs to overcompensate for the work electrode, and wear the packs prematurely.

The car hasn't run or idled roughly since that repair. On to the next problem.

The forum here shows Verona's were stalling due to an intermittent lean mixture called for by the ECM. The fix, according to history on this site, was to reprogram the ECM. The Natl Highway Safety Transportation website shows a recall to "reprogram the ECU".

I called Suzuki Corporate in CA last Friday evening. I was told that Suzuki's "KE" recall was to fix the EFI, not the ECM. I asked if there was a recall to reprogram the ECM but the customer service rep was adamant that no ECM recall was ever issued by Suzuki.

Okaaaay.

My local dealer records that Mom's car had recall work on the EFI done in 2004 and again in 2005. The recall was Suzuki Recall KE.

My Questions

1. Is Suzuka and the Natl Hwy Safety Trans referring to the same recall work when one says EFI (Suzuki) and the other says ECM (NHST)?

2. Could the EFI/ECM need to be reprogrammed again after being trouble free since 2005?

3. What else could be causing intermittent stalling?


Thanks to all here,
Sam

Hi Sam. Any luck fixing the issue? I've got a similar problem and posted my questions a few months back with no reply. I stumbled across your post and wanted to see if you found a solution. Thanks (hopefully) in advance!
