Help Me!! Missing Under Load

[Guest r33gtsttrout]

I have a problem!! its driving me nuts!! whenever im dropping back to second and flooring it my car seems to have a miss after a second. It lasts bout a second then dissappears.It does it whenever i really give it a bootfull. its mainly stock running 10 psi, and when im giving it to it it pops up to 11 psi for a brief second and this seems to be where it misses. its only starting to do this, and i've always had the boost set at this. yesterday i put new ngk iridium plugs, oil and filter, fuel filter, pod filter, injector cleaner, cleaned afm!!! guess what!! Problem still there!!!!

I've thought of maybe a boost leak, or fuel pump on the way out!! but i'm not sure!! I NEED HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!

reset your ecu. see if that helps

[sweetr33]

check coil packs are secure, im sure you have probably gone over all the things u can see in the engine bay

HOW?????

[sweetr33]

disconnect the battery and push the brake pedal afew time turn lights on whatever just to drain the resuming power from the system. Then reconnect the battery and the computer should be reset and re learn some sutff. Apparently it should be done after each engine mod so the computer can make the most outta it.

also heard that to reset the ecu you disconnect the battery and leave it disconnected for 24hours and reconnect it but i pressume that using the brake pedal and lights to drain the power out and doing it that way would still reset the ecu and is a heck of alot quicker

also hav eyou changed your plugs or upped your boost if so you need to gap your plugs to .8 or else this happens

try putting your boost down and see what happens, since its colder now maybe your overboosting and your car cant handle it

A couple more ideas....

1. Your plugs may be loose or fouled. If you've used octance booster, that sh#t fouls plugs.

2. If you have an aftermarket BOV, you may have it too loose and be losing boost from there on hard acceleration.

good luck

plugs new in on saturday. have aftermarket bov, gfb hybrid, not plummed back though. Can you gap ngk iridiums??? it says on box that you dont gap them

[meggala]

well the plugs seem to be the issue I belive you can gapp them but I have not done this personally I use coppers

Had the same problem. Was fixed on a dyno by adjusting the timing. Just another thing to consider.
