hey guys I recently bought a BA XR6T and recently its started to shutter the whole car wenever boost comes on, I changed the spark plugs and cleaned out the coils and cant see nothing leaking or anything that could cause problems any ideas on wots wrong?

try a new set of coils.

u arent alone there mike.

mine is doing the exact same thing and ive checked evderything as well. my plugs were changes 2000kms ago.

let us know how u go solving this problem and ill do the same

Also got the same problem and I'm just about to change my plugs tonight to see if it helps.

Considered engine mounts? Cheers

Is it running higher than stock boost?

BA valve springs are notorious for being weak, especially after

a few thousand km's. It could be valve springs struggling under

high boost and valve floating, it kind of shudders under WOT.

If you let it fall back to idle after it happens, and it runs rough

for a bit, that's probably the problem.

I changed the coils and all my problems went away.

here is a photo of what was wrong with the coil;

if u see anything like this on your coils replace them and u should be right.

good luck mate
