Misfiring Under Boost

[RICKYTURBO]

Ok I Need Some Help Guys, My Car Runs Fine Before Boost After That Aprox 3500 Rpm Start To Misfire (like A Rev Control) I Change The Sparkplugs Wires, The Coil Pack ( I Try With Two Different Packs) And Still Same Problem. I Would Try A Vacuum Leak Test. Is Can Possible The The Ignition Module ...any Ideas...

That sounds to me like you have a nice boost leak there

Check for it..I'm sure you'll find the problem and solve it

 

[MrBoxx]

What kind of spark plugs are you using? What are they gapped to?

 

[RICKYTURBO]

I Run With Ngk Gapped .28..i Would Change The Sparkplugs Today... Keep You Inform..

Your plug gap is ok. Which Ngk plug are you using? BPR6ES(stock plug)?

 

[1g_tsi_awd]

I am also thinking boost leak... your gaps seem fine...

 

[RICKYTURBO]

BPR6ES(stock plug) ...the thing that I'm thinking is a loosen plug... because the problem is intermitent I mean I made a ride last night and works perfectly but when I come back comes the misfiring... I dont know whats going on....

Is your mod list up to date? Are you using any tuning devices?
