Seriously, cut out the crap information.

QFT.
DarkHorizon, you dare say I cluttered up a thread with useless advice?
You're a real jester. :th_jester:

Yea i know what u mean . Im gonna give it a shot and change the front injectors because on the other motor all the three fronts chipped and that engine only had 25000km . I will also change my fuel filter too and get injector cleaner and shove that in the tank. If theres anything else i should do let me know thanks:)

Swap the fuel rails...

Maybe by some crazy chance they are clogged?

I dont have fuel rails .. Only other rails i have is the gt 3800 rails is their a possible way to blow out the old rails to clean them? And what are the odds of it doing this right after i put al 104 spark plugs in ? I did gap it at 52.thou . Is it possible that my engine dosent like these plugs? I am running stock pcm still is it possible that the stock pcm and the AL 104 plugs dont work togethor without a tune??

Okay update . I hooked up all the injectors to a 6 volt flashlight batt one by one and they all work great and sound the same as for the rails they seem very clean inside. I remember i had took off the screen on the trottle body intake maybe it ssucked in too much air and leaned out ? I put the screen back in now and will be finished the car tomarrrow. Anything else u guys might think the cause was ?

Umm the screen not being on causing the fuel tables to be all fvcked up. Think thats the problem maybe, Chipping the same one both times dumb luck IMO.

Yea i put the screen back on and hope for the best:)
