I have a coupe 2.2L '06 LT. It's a beater so it has quite alot of issues but as a college student I just need to keep it driving. So over the last few days while turning right and accelerating (easy or hard) It studders, like it's going to stall and losses power and then just jumps back to life as I straighten out. I've put it hard into a left hand turn and tried it slowly and no issues there. I could not find a similar issue through google involving any other cobalt. I did however find the issue in other cars, most of which point too the fuel pump going out and it being located on the right hand side of the car. I guess the turning sloshes the fuel to the left + it going out means loss of power. I did research the tank in mine and It looks like it's pretty much in the middle. I did fill the tank up just to test and it still happens so maybe a MAP or MAF issue? I'm unsure and I can't really afford to just drop it off at the shop. Any help is MUCH appreciated. Btw if anyone wants to give me a SS Sedan TC feel free haha.

:edit
I hope I didn't break any rules and this is in the right area. If I did, my apologies.

Also Very possible your fuel filter is clogged with trash and/or trash has made its way into the
rail. Have ran into it a few times also trash accumulated in tank near pickup causing fuel starvation during certain driving maneuvers.

 

Posted correctly. No worries.

 

Well now its having a real hard time starting too. Starts and all then bogs out and stalls. I really need to figure out the issue so I can fix it or I'll have no way yo class or work...

 

def could be a lack of fuel pressure/flow

 

Ways to check this? How to figure what needs to be replaced/drained?

 

Engine light just came on going to research the code after class.

edit: the engine light went away haha smh. Just to clarify, the car has no shuttering issues or anything unless it's starting up or turning right. I can "pull" fine any other time. Such a weird issue. How would I go about cleaning the MAP, MAF, Fuel rail, Fuel line, or fuel pump?

 

they make a MAF cleaner take that and clean your sensors do not wipe them off let them air dry before re installing. as far as the other stuff dont know how to clean that stuff. i dont think your fuel rail is bad. like the others said, it could be your pump thats clogged so may have to replace that one since you may not be getting the correct flow or pressure

 

Thanks for the info. I guess I should just replace the fuel pump. Anyone in FL selling an SS?

 

The only reason im suspectant of the rail is how the concern append when turning. I would pull the fuel filter first (i think yours has an external one) and see how full of crud it is.
Your year should have a service port for checking pressure and volume on the rail.

 

Codes I pulled today.

P0171 System too lean. Bank 1

P0121 TPS/PEDAL POSITION SENSOR A CKT RANGE/PERF

So the MAP sensor and the Throttle body pedal sensor are throwing codes. Any Ideas for a quick fix? It's still running rough as hell and has a hard time cranking up like it's not getting fuel. No other codes were present. My fuel filter is external btw.

 

Bump. I'm desperate for a solution. I don't want to buy a map sensor/fuel filter/throttle body/fuel pump if they don't need to be replaced. If anyone is near Orlando I'll meet you up to 50 miles to have you look at it. If this car breaks I'm screwed.

 

if the car is throwing those codes, pull the map sensory and the throttle body and clean them with maf cleaner and throttle body cleaner and see if that will just help out a little. i know my car just started running rough but nothing like yours and my intake manifold map sensor went so i tried cleaning it but it didnt work lol. so i have to get a new one lol. if the fuel filter is external check that as well and see if its all caked up and that will be an easy fix as well.

 

Well someone pulled out infront of me and I totaled my balt. So thanks anyways.

 

wait what??? you ok???
