Title: Bad injector symptoms?
Post by: Jeff@TheQuadShop on January 22, 2006, 07:13:44 pm
What are the symptoms of a bad injector? I just installed a new 1.9 longblock and now the motor has a shimmey too it. I notice it mostly in 5th gear at around 2000 rpms.  :x

you would notice it in every gear, not just 5th. you probably have a tyre issue.

I know its not the tires as it didn't do it before I installed the new longblock. It does it in other gears just not as bad as 5th. The motor is also shaking around some at idle.

It was the injector, one of the needle valves was stuck closed. When I freeded it up, the very sharp part of the tip broke off(so small its hard to see the piece that broke off). Its running good but I'm assuming it has a bad spray pattern now. Does that sound about right?

I read the tire issue before penetrating you're question.

I would say a faulty motor mount...even though it was fine before. Forgot to tighten something up?
