Alright Guys I am at a loss on this one. I have an 06 Chevy Cobalt LT Sedan with 120,000 miles on my car. I have changed the fuel filter, ignition coil pack, and all four boots, and spark plugs but now when I am driving around 10 to 30 mph my car stalls without warning. I am at a complete loss. The only thing I can think of is either the Crankshaft Position Sensor CPS, or the Ignition Control Module ICM. My car did fail the annual inspection emissions test and the trouble codes states the Crankshaft Postion Sensor is bad but I took it the Chevy Dealer I got a complete diffrent story. They told me that the coil pack and boots were bad. They also said that I needed to put those crappy AC DELCO spark plugs back in my car because right now I have the E3 spark plugs in there. To sum it up I have changed everything but the ICM and CPS HEEEEEELLLLLLLLPPPPP!!!!!!

 

never heard of an issue like that

 

Yeah dude it sucks lol and it is bugging me..

 

In that situation Its usually the cps as far as Im concerned.
What were the codes,if you could post them it would be a lot better.

 

Your car throws a CPS code, yet you replace everything that ISN'T related to the CPS?

...

 

You got emmissions, they told you what it was, why didn't you just fix it after that?

They have no reason to lie to you.

 

Well no if you guys would have read the whole thing you would have seen that when I took my car to get inspected it failed because the trouble codes read CPS well then I took it to the dealer to have it this CPS dealt with and they checked my cars computer and it said my cars computer already had the latest calibrations and thats when they looked at the ignition coil and the boots and they got trouble codes that said fuel. So thats when I have changed everything but the cps so I am in the process of working on that.

 

So they told you what was wrong, you then took it to the dealer, and they said no, Soooo thats when you tell them to fix it, replace it, whatever the case, becouse you failed emmissions becouse of it, and they fix whatever they found wrong too.

I guess I am missing something.

 

Im missing it to.
I know Im not that slow !!!
