hey everyone I have 03 evo VIII with 24,000 miles on it. i have few mods, i have this weird hesitation problem it happens no matter if im stepping on it or just half throttle. It will be fine to about 4 grand then it drops to about 3,800 and then slowing kicks up like lag. so basiclly it drops then hesitates like lag. i dont think its lagg i watch the boost gauge and it seems right it hits 19 and then drops off to about 16-17. people told me its the clutch but it doesnt feel like its slipping and i can launch it perfectly. another friend told me it was my coil pack or something with igniton. i changed the plugs and put in a walbro 225 fuel pump. anyone know whats going on.

 

I was going to say change out your plugs but i see you already did that. Maybe try a different plug gap. What on your car was changed before it started acting up or did it just start happening out of nowhere? Good luck.

 

do you have a mbc?

 

reduce the gap to .025 and let us know.

 

yeah i have a mbc and i ordered the plugs from aa and they said i didnt have to gap them but i will check the gap
