Slight jerk or bucking merging on to highway, advise?

I can only dream of 21mpg. Live in the city here in Phoenix, AZ and only pull around 14-17mpg

That sounds about right for the city.

...and that's when my wife drives it... when I drive the EX I pull around 12

me too

mine is missing too as light throttle and low rpm mostly in high gear.. starts at 1250 rpm, definately feels like at least one cylinder missing kinda bucks, then clears up at 1500 rpm.. if you stomp it it blows past it no problem.. wanna nip it in the bud.. has anyone had diagnostics prove a bad coil on a
3v? Or have plugs usually fixed this for most?

The plug change pretty much fixed this problem for me.

thats what I was hoping to hear! im still under warranty for 2 more months.. so gonna try to get dealer to fix.. but ya know its amazing they can never seem to duplicate the problem.. then chrg 100 bucks for diags. that i gotta pay since they couldnt find anything.. until the warranty runs out of course.. then lots of expensive solutions! Im gonna bring a service guy out w/ me and show him.. hopefully I can talk him into hooking up scanner as i drive too to ensure he gets it!

Did the Mass Air Flow or PCV get any gunk on them in the proces that might be making your truck run too rich?
