Sputter or backfire at same RPM.

[Boostdclips99]

Have a weird issue with sputtering and the occasion backfire at starting exactly at 2200-3000 RPM. It doesn't matter whether I am WOT or just cruising, the car will sputter and "hit a wall" then start boosting suddenly.

Ran a boost leak already with nothing major. I just got home and haven't checked plugs in the past few days but I checked them a few weeks ago. Will check again tomorrow, anything else I should look for?

UPDATE: Changed the plugs, but it did not help. Now with a dsmlink log.

How is your coil and your control module?

Turned out to be right. I swapped the SBR COP with the stock coil and the miss fire went away.

I thought the problem was fixed but its back. I still have the wires and coil packs of but it still has a pause like it "hits a wall". Please help, I now have a log posted.

hey...i had a similar problem earlier this year, it was like it was hitting a rev limiter at low rpms. http://www.dsmtuners.com/forums/newbie-forum/373008-i-need-help-am-i-hitting-fuel-cut-what.html
It might help, with my problem i ended up having to rewire all the wires underneath the coil packs. Idk i gave it a shot
