Default Re: New ZR-1. New Issue. Stalling Once Warm.

Your Code 61 indicates trouble in the Secondaries system, probably because there is a vacuum leak avoiding the ports to open properly. Is the vacuum pump (located in the very front right corner under the hood) running at startup for a few seconds and then cycling every few seconds? If not it may already be stuck or burnt, if yes and it keeps running there is a vacuum leak.
As far as the injectors are concerned you will find a good guide how to measure their resistance here: http://zr1specialist.com/HAT%20Web/articles%20index.htm
Marc's page is generally a great source of highly valuable information and so is Marc himself of course. You may consider his service to resolve your issues.
If your car shows injector issues these have to be resolved immediately as faulty injectors can cause a lot of trouble down the road.

Again, good luck!
