Replacing Injectors - ZR-1 Net Registry Forums

QB93Z · 04-01-2010

Last Sunday we replaced the injectors in George's 1990 ZR-1. The car does not have many miles on it and the injectors were original.

The results were the car performed significantly better with new injectors.

When I measured the injector coil resistance of the old coils, I found 4 that had low reisitance.

My measurements were taken at room temperature. Most of the injectors read 12-12.5 ohms. Three of the bad injectors read about 6 ohms.

If you still have original 1990 injectors in your ZR-1, I suggest checking/replacing them.
