i have a question whenever i slam on the gas (WOT) there gets a sputtering effect. i dont know if it is the plugs. so i am asking anyone if they have a suggestion as to what it could be. it feels like it isnt getting enough fuel....

 

Did you buy the car used with all those mods or do them yourself? You make no mention of a reflash or stand alone. If you or someone else slaped all those upgrades on there with out a proper tune, that's your problem right there.

 

If you list mods/tunes in order, it will help. Include when you change spark plugs

pull your plugs first..it could be a number of things.. we need more info to help you better..

 

Where are you located, and what's the weather like in your area? More importantly, has it been cold lately?

 

i am located at lawton, ok. it's been hot and cold. i changed the spark plugs about a month ago. i got my power fc tuned at mzm performance. the problem just started happening. when i drive normal it is ok. when i hit the gas hard it starts sputtering picking up speed slowly.

 

i had a boost leak....and it did the same thing.....check ur vacuum lines to ur boost controller

 

thans a lot ludikraut and everyone that gave insights. that forum u gave helped me out. it turned out to be the coil pack. thanks guys...

 

good... problem solved.

 

When I have experienced this problem it has usually been due to a poor connection in between the plugs and wires. This was back when I was running aftermarket wires. You just can't beat the solid connection you get from the oem wires.

edit: oh and like smoked I repaired a few stripped out coil bolt holes in the valve cover but the problem still occured until I went back to stock wires.

 

Rock on.
