Firing order
I have a 1990 F250 with a 351, it runs rough at idle in gear, so I did a tune up, the whole nine yards and it is still rough.
I went to check the timing and followed the instructions, but when I put it on the #1 plug wire it is 180 off from TBC but when I put it on #7 it is 10 degrees TBC.
Can anyone offer any help as to what my problem is even if it is the firing order?
Thanks,
Chris
