Hi I'm having an issue with my Z it starts up fine then 20 seconds later she runs like a pig, spluttering and popping, I can rev up and drive her but she's not right, I have changed the plugs but no change????

Injector connections, commonly go green and cause the exact problem you have, if left the injector will often go open circuit and require changing.

Thank Jeff I'll have a look

Yup - I had the same problem... Albeit the misfire would often disappear after a good long run. Jimmer cleaned the connectors and covered them in a protective grease, now all is well again..:cool:
