91 ZR-1 Cutting Out Under Load - ZR-1 Net Registry Forums

Still trying to nail this cutting out under load problem down. This problem is something that just happened out of the blue, didn't slowly get worse. It also doesn't matter if it's bone cold or completely warmed up, same cutting out under load. Given that, does it still sound like an injector problem? I just don't see how one injector can make the whole car feel like it's falling on it's face.

One weird thing, this happed just after changing computer chips. I had been running a Rippie chip for years but it must have been a really old one because the car always idled way too high which was driving me crazy. I got the redesigned chip from GM that address that issue. I installed the GM chip the day the problem hit. Upon installing the GM chip, the car ran fine, idled correctly and I took my Sunday drive. It was later that day that the problem hit. Thinking that the chip might possibly be defective, I reinstalled the Rippie chip but the car still cut out just the same under load. It doesn't matter which chip is being used, same problem. Just thought I'd mention this. I can't image the chip change screwing something up but who knows? Anyone see any correlation?
