Re: New ZR-1. New Issue. Stalling Once Warm.
I have the Red Devil River Bluetooth connector. It works but can be glitchy staying connected. I hear the 1320 Electronics piece is less so.

Re: New ZR-1. New Issue. Stalling Once Warm.
Fuel tank emptied. Relatively clean inside, but the gas was old. Cleaned out and fresh gas put in. Still idles rough when warm, but doesn't stall anymore. A step in the right direction.
So what else happens when she gets to operating temperature?

Re: New ZR-1. New Issue. Stalling Once Warm.
Stupid question, but have you cleaned your battery terminals? Doesn't hurt to take a wire brush to them. Your problems don't sound electrical, but you never know.

Re: New ZR-1. New Issue. Stalling Once Warm.
Electrical resistance changes with temperature, so I agree with rush91. But everything electrical underneath the hood could be the issue, including injectors, coils, etc. I know you said the PO replaced the injectors but it may be worth checking their resistances cold and hot. Never done this myself but IIRC Marc Haibeck had written a procedure.
Edit: once it's running, the alternator would be more the culprit than the battery. |

Re: New ZR-1. New Issue. Stalling Once Warm.
The one odd thing is that it ran ok until the first fill up. The issues started immediately after. But I'll keep checking everything!
The car has been well kept by a loving owner. I think most of the issues stem from why he sold it. That is, he just hadn't been able to drive it much over the past few years.

Re: New ZR-1. New Issue. Stalling Once Warm.
Have you put an ohm meter to the injectors yet? I know you said they were replaced, but Id still check them after warm up...

May have to look into what's involved with that. Is that a plenum off deal?

Re: New ZR-1. New Issue. Stalling Once Warm.
I had a car that did exactly what you describe. Injectors failing after warming up was the issue. I've been told even new replacements can fail, although I have not had that happen thus far.
