Doesn't sound like a great idea to go far far in this condition.  I did a top end rebuild a few years ago and shortly after developed an un pleasant misfire.  Eventually it was the HT leads.  Maybe the poking and prodding around isn't good if the leads are old.  Could try running it in the dark and checking for any signs of arking but unless the leasd are relatively new i'd try changing them...

The 2003 V6 has coil packs sat on top of the spark plugs so no plug leads.

I agree that all the pulling and pushing may have upset some electrical connections though :(

Check the wires at the injector muiltiplug, There are eight wires here, one for each injector and TWO positive supplies, one feeding each bank of injectors
