Put in the 7243 and new Motorcraft wire.....now truck runs like crap!!! It idles and runs like a bucking bronco. Double check the connections, made sure I didn't inadvertently knock anything loose. As far as I can see, I didn't. Anyone has a diagram of the arrangement of the ignition module? Pretty sure I connected them correctly, but want to double check. The pistons are arranged 1-3 from front of passenger side, and 4-6 from front of driver side, correct? Very frustrating, can't drive my truck, good thing I have my motorcycle to get around. Thank you all.
Oh yeah, I did gapped them correctly, checked it twice at least.
Okay, I am an idiot. Find out what's wrong, don't laugh.......got my 1st and 3rd cylinder wires mixed up!!!!! I swear, for the last two days, I have checked and checked because that's what I thought I did wrong. No, I had no malted beverages during that time :-) Checked again today, sure enough, 1st and 3rd wire got switched, doh!!! Will let you know how the NGK work out.
