They are the only plugs that I personally would ever run in my car. NGK BPRxES. (he has the 6's i run 7's)

I completely burned up a set of NGK Platinum plugs in about 4 months of normal daily driving. I've had the set of regular NGK plugs in my car for about 8 months now, and they're still in really good condition.

Exactly. I tried Bosch platinums when i first got my Talon. The thing broke up badly in the higher rpms. NGK BPR7's for me now.

Did this ever get resolved?

Re: Hesitates after 7lbs...
 
i think i am having the same problem with my 1g...
ive done a boost leak test, new plugs, and after i replaced a bad injector, it was boosting great.... then i took it out again and was gonna get some gas, then it just stopped boosting after 2500 rpm..... i was wondering if its the turbo???? i checked the wastegate and it still opens but i could not control the amount of psi going in before it opened...

i might pick up some new wires later... thats what im hoping itd be....

Stopped building boost completly? How does the car run otherwise?

Re: Hesitates after 7lbs...
 
it runs perfect before boost... but once it starts boosting it just sounds like a lot of backed up exhaust built up... and no boost reading or goin through... but once you get up on rpm.... it starts to read a little boost...

Pull your intake and check your turbo for shaft play.

Another "test" is you can temporarily unhook your wastegate and CAREFULLY watch your boost. You should build boost and very quickly without boost control.

DO NOT let it swing past 15psi as that is all you need for the test.

Re: Hesitates after 7lbs...
 
i checked the turbo and ran the wastegate straight through... still same results...

Coudln't wires have something to do with that as well, not just the plugs... I mean they go bad as well.

Re: Hesitates after 7lbs...
 
i replaced wires too... not that... im gonna do a more thorough leak test this weekend... im pissed!!!

Re: Hesitates after 7lbs...
 
So you completely unhooked the WG line, and you are not building boost? Am I understanding this correctly? If that's the case, I'd look at your turbo.

johnson 03-14-2008 12:01 PM
Re: Hesitates after 7lbs...
 
it still feels like it wants to go but it just cant... you feel power/ no power/ power/ no power... i think the turbo is still boosting, just not through the motor or somethin... beats me... i dont wanna replace turbo in a car i dont plan on keeping!!!

Halon 03-14-2008 12:34 PM
Re: Hesitates after 7lbs...
 
You think it's boosting? Do you not have a boost gauge? If you don't have a boost gauge, that should be one of the first things you get for that car.

Something else to check is your ignition timing. Check that and tell us what it's at. If you are in fact boosting just fine, but the car is extremely sluggish, your ignition timing may be off, causing a ton of knock, which is what is making your car accelerate so poorly.

What did your BOOST GAUGE say when you unhooked the wastegate?

johnson 03-14-2008 12:53 PM
Re: Hesitates after 7lbs...
 
same thing as it had all along...
nothing until maybe 3.5 rpm then about 7lbs...

There, was that so hard? You need to provide as much info as possible when you're having others trying to diagnose your problem over the internet.

So with your wastegate unhooked, you're seeing a max boost of 7psi by 3.5k rpm's, and it never goes above that? Assuming your gauge is installed correctly and reading correctly, I'd say you either have a MAJOR boost leak, or the problem is pointing to your turbo/wastegate.

Winner!

Here I will write a proof for you.

If no boost leaks, then dead turbocharger.

If dead turbocharger, then dead exhaust housing or excessive shaft play.

case closed.

Does it spit and sputter some? When a car is misfiring it can do that type of thing. I would do a boost leak check first, then go from there.
