High RPM stumble - ZR-1 Net Registry Forums

dodgerroger · 08-10-2015

Anybody have any ideas of what to look at for sudden engine stumbling at about 6200 RPM. Does not stumble in first gear, but does in second and on when pulling hard. Car has only 15K miles. Thanks.

Since it's a '94 it probably isn't fuel injectors.
My guess, in order of likelyhood:
1. Spark Plugs
2. Wires
3. Coil Packs
