Ground problem
 

Hi guys,

Sorry for the dumb post ahead of time. Anyways after taking the UIM off to replace my turbo control solenoid I have severe bucking and hesitation. The thing is I have one 12 mm bolt left over and I'm almost positive it is a ground. After taking the thing apart many times I still cannot find where it goes. The three grounds I DO have attached are... the one on the coil rack, the clip on the passenger side and the one on the back of the UIM with the 12 mm nut. Please help my forgetfullness!

Thanks,
Rob
