Misfire after 3000 RPMS

[98mitsubishigst]

Hey ladies and Gents.

I am having a weird misfire after the car warms up to operating temp only when going into boost. The car idles fire and is fine at low rpms for putting around. As soon as the turbo is about to get into spool, or after half throttle, it chokes out around 3000 rpms. The worst is trying to get up hills, the car doesn't seem to want to move and i creep up hills.

Little background of the car, Just did the AWD swap, HX40 turbo, Tuned on e85 on Speed Density and ECMlink v3. The car sat all winter, and already ran new e85 through the car for about 300 miles. New 255 pump over winter.

I replaced plugs, wires, o2 sensor last year, but after car sat all winter, i suspect parts could have gone bad. My car also runs hotter than most dsms and i in turn feel like the o2 sensors shit the bed faster than average.

I have posted a log file, just noticed by wideband wasn't reading but you can see around 3000 rpms that the car starts choking out!

Thanks guys!

I Havnt looked at the log since my pc is out in the shop, but if it is going lean at the misfiring, you may want to have the injectors cleaned. Or do it yourself using carb cleaner, and a YouTube method to activate the injectors. I just went through this very issue myself.

Have you done a boost leak test and checked all air tube clamps for looseness?
