Can you provide a detailed description of the symptoms of the issue you are having? Telling us what is in your build is not going to help.

Also, please separate your sentences with periods and other punctuation marks. Otherwise, readers will spend more time trying to figure out what you are trying to say, rather than trying to think of a solution to your problem.

I would start with the computer. An OEM ECU will not work with the equipment you have now. If all your hardware is new and installed correctly, the most likely problem is fuel management or timing. If you have the correct ECM with for the motor, your only option is to get it professionally tuned. Otherwise, your turbo is useless.

vtechachey

it was white like that but it was all the way on top of the plug

vtechachey

tuned on crome

vtechachey

it can't be fule cuz the car was running fine

vtechachey

and i for got to tell u if i get on it out of 1st it will go with no sputtering

dpetro1

what are your plugs gapped at? does it only "sputter" in boost?

vtechachey

.022 and mostly when im boosting and my boy has a b16 turbo and it's gapped at the same and it runs fine

dpetro1

thats an ok gap. i would have the tuner look into it. i could be numerous things. i would check the timing, map sensor, tps sensor

vtechachey

i had the guy that tuned my car look at in lasnight and he don't know what is

vtechachey

bumpppppppppppppppppppppppp

Scuderia813

i've had this before and it was a bad map sensor. it was breaking up just past vtec. a quick change and i was back to boosting.

vtechachey

how bout on low end did i feel like it didnt have much power???

dpetro1

what have you done to troubleshoot? we gave you a few ideas, have your tried anything to try to narrow down the issue? as you test things you can start to rule out certain problems.

another idea is to swap distributors

vtechachey

im wating on my frend to get the dizzy

vtechachey

ok i put a nwe dizzy in my car but that didnt work

dpetro1

ok so its not the ignition, start testing sensors and checking grounds. are you sure the timing is correct and the motor is healthy?

vtechachey

ya the motor run's mint i will look at the timing but i don't think that is it i will let u know later

Crazy_SI_T

does anyone think it could be a minor leaky head gasket. he says it happens in boost, so when it build pressure fluid could be doing it? also i personaly think that those injectors couls be a little small, whats everyone else think. and 1 more thing. who is your tuner??
