Hey guys,

So i took the car out tonight for a little driving and when i floored it in 2nd and 3ed i felt a "splatt" or a pause. It would do this around 6k RPM.

Ex) when i floor it it'll start pulling then all of a sudden pause for a split second and then back to pulling a little more.

Is the car knocking? Im running 93 from shell. Does anyone know what could be the issue? The car is bone stock still. Any advice would be very appreciated!

Thanks

 

model/year?

 

guessing you have an old ROM like 0015

 

I have the 2008 GSR. Im not sure if i have the updated flash. I will have to call the dealer. Also, can i call any dealership for this check up?

 

No CEL or backfiring going on?

I've watched Tephra's KnockCEL flashing a few times and didn't sense *anything* being wrong with the car. If you felt it then it was probably too much fuel or a misfire. Misfires will throw a CEL if they are frequent enough.

 

No CEL or Backfiring going on. This wouldn't be what you guys call the hesitation right? Sorry, im pretty new to the car and never had this problem with my other vehicles

 

I'm having the exact same problem with my car, Recently threw a p0234 code during those pauses while flooring it, I'm still trying to figure out what my problem is, I'm tuned to 22 PSI, so I should not be overboosting, I'll be in contact with you when I find out whats going on buddy.
Meanwhile:
Any Mods?
Are you tuned?

 

Here's a link to my thread, hope it helps

 

Its good to hear im not the only one..but still

Currently bone stock, no mods, no tune. Ive had the car since wednesday and it just started happening yesterday. Do you guys think is may be a loose hose? Since im stock and currently still under warranty, do you guys think i should bring it into the dealership? Would they cover it?

 

What are the rpms associated with the boost, pause, boost?

 

take it to a dealership and get them to put on the most recent flash.

u probably have an old flash...

 

Should i call them ahead of time or should i just go up there. The dealer i bought the car from is about an hr away, however there is another dealer just a few miles away. Is there a fee for this service?

 

You should call them.

Technically its a TSB so it should be free, but it might already be done.

Check under your hood for a TSB sticker.

 

I think it hasn't been done. I have did some more research and people say its the rich tune from factory. I also to have weird idling at times, hesitation and the stuttering in higher RPM's. I will definitely give the dealer a call and bring it in.

Does anyone know about these fuel pump relay's and if that is a recall? I really dont want to lose a motor

 

could be from the rich tune, could be from a bad relay.

could be from the FPR hose popped off...

just call the dealer and tell them you want to check that all the TSB's/recalls have been done...
