Sudden misfire after restart - ZR-1 Net Registry Forums

Tom,

Sounds a bit like my warning symptoms when my primary injector coils started to short out. One start cycle it was okay and then a slight miss and then a worse miss & worse & worse till it seemed like it was a 4 cylinder. Check for codes & if none then scan it & the fuel numbers will tell you something....if the coils short out usually it goes lean & sometimes if it's enough of the shorted coils you can smell the lean condition at the exhaust outlets.
