2006 cobalt ss/sc

Best way to explain it is...

Feels like the car gets hit with a big gust of wind every second or two only in the first and second gears during acceleration then goes away. It feels like im hoping on the gas in first and second.


I wanna say its a vacuum line but i dont know where to check and I dont think i hear any whistling.

 

did the light ever come on? my light came then off, then i had that problem faulty connector somewhere under the hood. good luck

Sounds to me like fuel cut? What are your mods?

 

100% stock no CEL. Going to do a 40k tune up this weekend.

See if it dosent fix the problem. No idea what it could be going to check for vacuum leaks also.

 

hammer usually fixes ****...sry i couldnt help you

idk my guess is plugs or clogged injectors, but im probably wroong

 

Fuel filter ever been replaced? Clean your TB lately?

 

Doing that this weekend.

: Actually :
Clean TB
Clean Maf
New Cabin Air Filter /// AC Delco Part #CF125
New Air Filter /// 15239447
New Spark Plugs /// .040" /// (15 lb ft) /// NGK PFR6T – 10G // OEM 12787099
Fuel Filter Change /// Replacement Fuel Filter 22734980
Change Trans Fluid /// Royal Purple Max Gear 75W-90 2qrts
Install INGALLS Engine Damper

Hopefully that will fix the problem. Idk though im due for that stuff though.

 

Probably TB grime or something. Only happens at part throttle, right?

 

it happens during first and second gear shifting like go into first accel and it feels like gust of wind hits on and off.

kind of like hopping on and off the Accelerator Like depress then let off depress then let off. then get up to speed then shift into 2nd then its gone.

Weird i know lol But if i take it slow and gramma it then it dosent do it.

 

Thats what I was thinking.

All this should fix your problem and do you up good.

 

Update on my progress.... LoL @ the upkeep on this car. Note I bought this car used.

Unplugged Battery For 1 Hour to Reset Computers.

Changed Cabin Air Filter


Changed OEM Air Filter: Need to find OEM Filter /// Cannot find One that fits stock Air Box.


Changed MAnual Trans FLuid To Royal Purple

 

Day 2 Going to put airbox back in car and take her out for a test drive.

AirBox Mod While i was at it...


Old fuel filter


Old Spark Plugs


problem fixed... Just needed a good tune up

 

That air filter looks horrid. Also, just an FYI - unplugging your battery doesn't do anything useful except clearing your radio settings.

 

5 visits back to the Dealer for the SAME issue you are having on my 2009 Turbo SS, that's right, 2009.
Submitted paperwork to declare it a Lemon since 2 different dealers couldn't find a problem with this INTERMITTENT situation!
Of course when the GM management guy shows up from far away to drive the car for a day, the car acts perfect.
This all started right after break-in at 500 miles, and still randomly just happens for part of a day, then goes away, even after approaching 10,000 miles now.
Of course our dealers down here act like they never seen nor heard of this problem.
That's probably for real because I've yet to see another 2009 Colbalt SS in our community of 75,000 people.
If you get an answer, I'd love to hear about it?
Thanks and Good Luck.

Mine surges slightly when cold and I have the bouncing idle but I have a TPS CEL. Drive fine when warmed up. I should probably do a tune up myself.

 

Mine does this too. Usually in 2nd & or 3rd/4th gear.

New set of plugs always clears it up.

 

Doesn't it reset the fuel trim's too?
