Ok so say you WOT and gauge shows full boost but rpm's are slow to rise above 3k and speed is slow to rise as well.
Sometimes it all the sudden kicks in and u feel it and rpms jump up and so does speed - boost gauge still showing normal full boost.


Car is 100% stock except for normal maintenance.
82k on the clock.

No cell or anything.

Any ideas?

 

limp mode

 

Wouldn't that throw a cell?
Or show or say something?

It does get above 3k just not very fast.

 

Intercooler pump

 

And a little to the left

 

clogged cat...

 

cobalt with a vtech and a turbo

 

^^ Good Answer.

or

Something is causing ALOT of kr...

 

ic pump works fine.
wouldnt doubt the cat...

not sure about limp like i said it gives no cell or msg..

what about clutch slip?

 

if it was clutch slip im pretty sure youd be able to feel it.

 

get the cat checked out should be under warranty

 

not clutch slip. It's most likely a clogged cat. A lot of people here have experienced the same problem, and have reported the cat being the culprit. Although, if you really want to rule out clutch slippage, turn the car on and put it in 5th. If it stalls, your clutch is fine; but if the engine stays on, you got a slipping clutch.

 

this sounds so much like when my clutch went out. i would hit it and the boot would jump way up and the car wouldnt go anywhere.

 

Rpm's go up when the clutch is slipping and you don't go faster. What does the car sound like when you get on it?

 

when i get on it, boost goes to full, rpms stick around 3k slowly rising and i mean slowly.
lack of power, feels like u just aren't going anywhere, then all the sudden it may take off
or not.

umm it sounds kind of odd..
i dunno how to explain it, it doesn't sound normal thats for sure.
kind of higher pitch....then i would expect.

 

check your vtek solenoid

 

cat my friend..

 

sure your not in 5th gear in a 40 roll?

 

rotflmao more like any gear at 2800 or 2900 or even 3k at that...doesnt matter
gun it and u get full boost with pretty much no power..
now i can say the cat does not glow...

 

Cat or BPV?

 

what about boost control module?

I know that the back nipple on mine spins around...
I don't remember it doing that when I got it...
so maybe it has a leak from it? i dunno.

anyone else nipple on the back of it spin around?
