The problem im havin is that thewire that is connected to the injector when moved makes my engine run hard (shakes). What can i do to fix the problem.

 

I'd check the Connection ... Sounds like it's either loose or it broke the wire to the injector moving it causes it to disconnect or ground out causing it to miss ...
I'm assuming this is a new install ...
If it's an old install the tape/insulation couldbe worn thru ir the wires broke from flexing ...

 

Yea i had it done back in March of this year. The wire is clamp to the wire of theinjector. When I have the wire disconnected it doesnt run hard.
