* * Need Help with Diagnosis!!!!!!

[Garman112]

My car will boost real hard but it feels like the car cuts out when it starts boosting n wont go no where and it still boosts... i cant find the problem can somebody help me?

I'm not sure if im understanding what your trying to say. Are you saying when your car starts to build boost the motor cuts out? Or when you reach a high rpm with maximum boost does your motor cut out?

Is it missing or does it just fall on its face?
Is the car modified?
What fuel type are you running?
Do you have serious vacum leaks?

You need to explain a little bit more, it sounds like your saying that at WOT your building boost but not feeling the power? if thats the case check the MAF and make sure your getting an accurate reading.

Any Check Engine Lights?
Search on how to do a boost leak test and try it.

Fill out your profile so that people can help you out in the future...

knocking maybe. maybe hook it up to a logger. you should be able to find the problem then

Boost leak tests are your friend if you havent done one yet.

I would think it was engine knock. But please explain your problem a bit more.

Along with a boost leak test, I would also check your plugs and plug wires as well.

When my motor starts to build boost it like the car falls on its face, and it still continues to build the boost but its feels like the power cuts off. I just got it together from putting a new trans in so i didnt have time to update my profile, the only thing done to it is flywheel, pressure plate n clutch, bov, o2 dump, the plugs n wires r new
