This is what I was going to do Bob, but I just thought that since my stock
injectors have 130,000+ miles on them, while they are off my truck I should
get them fully cleaned and balanced before I go ahead and swap them back in.
I have never seen the plugs in this condition when using the stock
injectors. I think the FMS#19s have been in for 7,000 miles or so and during
this time I only replaced the Autolites one time, currently on the second
set of plugs, which have about 500 miles on them. Should I have the stock
injectors cleaned/balanced you think and then put them in along with a fresh
set of plugs? I mean Autolite Coppers are only $7 for a set of 6 plugs. I
guess this way I could find out if it is/isnt the FMS injectors causing the
rich running condition. Then again, I would have to dish out $100-$150 to
have the stock injectors cleaned and balance. I just woul rather not put
dirty stock injectors back on my truck. Thanks again Bob, and others.
