My2000 SLT 4.7 is getting injector 7 codeP 0207. We switched injector 7 and 1 and get the same code. Now What????

Maybe I should have given more info in the beginning.

The engine doesn't feel like it is missing, but itis surging at an idle and when driving. It is also shifting irradically, meaning it is shifting when it shouldn't be.

HELP ME!!!!!!!!!!!!!!

 

Ck the ground wires at the engine block and replace the TPS.

 

I changed the TPS and it seemed to fix the surging and shifting problem. Howevernot enough miles on to tell about the 0207 code yet, but so far not today. Don't know where to find the ignition block so I can't check the grounds.
