misfiring WOT!!!!! help

[johnalomu#11]

I have a 1g dsm with a bunch of mods, when i am wot the car misfires quickly and you can tell there show be more power!!!!!! it has a noticable mis when outside of the car, it isn't a louud single backfire type miss, but a consistant one, like 10 misses/second type and only happens when under full throttle and at above 3800 rpm(basically once the turbo fuly kicks in)....... i know to check the plugs and wires but the wires are 6 month old ngk 7.5 mm and the plugs are new bre7es i think!!!!! do you think it could be from improper tuning or something else????

sometimes wires can die quick. Your problem sounds like one I had before and plug wires fixed it.

Try gapping your plugs down.Try .028" and if you still got problems then go to .025".

How many miles are on the car? If the milage is high you may want to look into the Mopar Combustion Chamber Cleaning on the VFAQ and discussed in more threads on here than I care to remember. My car was doing something similar, not after the MCCC!

You may also want to re-tighten all of your turbo piping and intercooler piping connections. A boost leak will certainly make the car run rich since you're adding fuel for what the ECU thinks is there. If it's leaking out, then it's running pig rich and that'll create the WOT stutter you're experiencing. Also do the plugs and wires as mentioned above.

Good luck and let us know what happens.

suprised or not, nbpres7's wont last that long, I change mine every 3 months.

pull out the plugs and check them, and make sure the spark plug wires are all the way in

ive heard that the bpr7es are good for 17+ lbs daily and anything under that fouls them out, is that the problem your having ?

i am only running 14 psi at the moment but with all my mods that boost feels like over 20 on a small turbo!!!!! please let me know what other spark plug would be appropriate if i plan to run 25-30 psi and the propper gap also, thank you for the reply!!!!!!

I drive a lot on the highway with the cruise on to avoid tickets-and this fouls my plugs. A few strong pulls in 5th up to 5500-6000 burns off all the deposits and all is good-no more bucking/misfiring. good luck!

I found the problem!!!!!! I regapped the plugs to .028 and put them back in,and re-tuned the car so the O2 was at 0.89.(Leaned it out) Luckily it wasn't the wires or a bigger more expensive problem...thanx for all the help guys, its really appreiated.After we got the car tuned we took the G-tech out and ran 12.5 1/4mile and 0-60 time of 4.4 @ 18psi.......Finally got a 12 Thanx again
