Developed a miss today. - ZR-1 Net Registry Forums

Took the car out this morning was running fine. Then about five miles later it began to miss at idle. You can hear the dual mass rattling. It appears to miss under load key on and off?

No DTC codes on a 12

The injectors were changed last year. I swaped plugs out two weeks ago with denso iridiums.

Original coils, wires, and fuel pumps to my knowledge.

With the key on the FP is 47 psi, after the key is shut off it dropped to 43 about ten minutes.

With the car running it shows 45 psi.

Any thoughts?
