Arrow inconsistent hesitation

......to #### and back, but whatever.

the car likes 2 hesitate lately @ lower rpm. it tends to do it more and more the longer i drive it. only between like ~2-4k rpm. i can describe the feeling as like a clogged ff on other cars.

i did the map and iac things. i also sprayed the h*ll outta the intake w/carb cleaner and even cleaned out the pcv valve.

it is an '02 w/~39k. stock aside from k & n.

idle is generally fine, doesn't stall, smooth acceleration, etc.

wtf?

thanx!

if its after driving alot, and happens during slow driving, it might be retarded timing by the computer from heat soak. theres alot of threads on 'bogging' that cover it. its pretty common.

Never mind...Why does the board say "incorrect use of one of the board files" when I try to delete my own post?

thanx. plugs r tight. color is also good. it started-up kinda choppy 2day, 2, but i think maybe b/c of all the carb cleaner from the other day. but i've started it ~5 times since then. who knows! guess the car hates the florida heat!
