just bought a gsx, unlimited stutterbox????

[george5366]

ok well, i replaced spark plugs, wires, o2 sensor(just ###), Knock sensor, even a throttle body (slight boost leak fixed) and bought an ecu non eprom, and guess what? its still a damn dsm. it still sputters. more and more i listened to it i think it might be a misfire all the way through high rpm past 5,000+. what else can it be? it does it at any boost level high or low. should i be looking into the market of an ignition coil? or module? i have bpr7es should i get bpr6es? please help.

Can't you get somebody from your local dsm club to help you out? You need another person to actually check the car out in person.

ignition coil replaced, runs better but still has the problem. last thing to replace will be the ignition module, which will probably be the last thing before i ram this car into a wall!!!!, it does have hard starts, so im sure that will help it. BUT ANYBODY ELSE HAVE SOME INPUT?

 

[george5366]

anybody?

Did you try and replace the fuel filter, plug wires? When i had a bad plug wire (brand new accel wires not even 3 months old) anything above 4500 WOT it would sputter,backfire...but if i leaned into it...it will gradually go past 4500 but then around 5000 it would start to do it. Try replacing that first and see what happens.

replaced very recently, right when i got the car
-fuel filter
-spark plugs
-wires
-throttle body (boost leak fix)
-igniton coil
-bought another non eprom ecu
-knock sensor
-o2 sensor

the last thing i ordered was the ignitor/module. ( because it does have hard starts) but other than that im clueless in what to look at after. WISEMAN NEEDED

im not sure if i want to buy the ignitor, if it really wont help me at all. im really feel like i want to start parting this bi*** out. i need some sort of input.

Like i said, you're going to need somebody to come over and look at it. You can't diagnose evrything over the internet.

Bumping is against the rules.
