I have recently but I could do it again. It seems to run good once I get into it but it seems like it might be a little leaner up top than it used to be. mainly I am dealing with this damn hesitation down low. I roll into the throttle and the wide band goes lean and it starts missing or sputtering (whatever) then it will start to kick in and seem to run strong.

this is what I have done so far. fuel filter, checked the fuel pump connections, and changed the spark plugs (they all looked pretty good).


edit: I am thinking about bypassing the SAFC to see how it runs.
