Hey guys i recently got a tune in February/march and the car ran great since then. Its a 2003 WW GSR and made 430whp. Manny should remember me....but neyway i got on the car the other day and it started to break up/sputter around 6000rpms. so i put in new plugs and made the gaps to .024 like previously and its still breaking up. What should i do. the car drives great at normal driving speed but once you get to 6000rpms it breaks up. let me know thanks.

 

I was gonna say changed your plugs but you already did. Is you MAS plugged in?

 

MAS??? whats that haha?

 

Your Mass Air Flow sensor on the intake?

Also check your spark plug wires and/or injectors...Do you have upgraded injectors? Maybe one is dunzo?? Just some ideas...

G/L

 

theres no mass air flow...its AEM EMS so....changed plugs already and checked wires. it could be injectors though. how do u check? they are a little nosier than usual. likea ticking/clacking noise

 

You got a pm joe.

 

Turn the boost down. It's colder.

 

did that happen to you Huy? it was running great up until a couple days ago. it ran great in the cold weather and hot weather..soo idk it might be the injectors cause i remember u telling me you had new ones and you were going to change them

 

Still waiting for your call joe???.
