Fuel injector electrical connections (misfires in 1, 2 & 3)

[deliriousga]

I've had a problem with cylinders 1, 2 & 3 misfiring but it's still going on after some fixes. I already replaced the secondary air pump (it sounded horrible so it was time) and replaced all three coils on that side and the plugs. I plan to replace the coils on the other side since I'm at 200k miles, but could only find 3 to buy at the time. I'm still getting misfires on that side so I'm guessing it might be the electrical connection to the fuel injectors. I don't think all 3 injectors would die at once. Anyone know where the fuel injector electrical connections are and if there is a connector for each side and if theyre easy to get to? I had a mechanic fix some vacuum leaks and that's when this started happening so I really think something is just loose.

Thanks for the help!
