Might have had a similar issue... one night was cruising 45-50ish cruise was ON and then the car stated to sputter like it wasn't getting either gas/air car was under 1/4. I would try to give it gas and nothing would happen. I coasted into a neighborhood where it idled terribly so i turned it off sat for about a min with it completely off. I tried to start it and nothing wouldn't turn over. Got towed home it sat over night and i tried to start it one more time and it turned right over with no problem.

I've never had the issue since. Also sometimes after i turn corners the car sputters REALLY bad..
any idea?

sorry if this thread jacks.... issues are related imo

 

No problem. I did some research and came across some good info https://www.cobaltss.net/forums/prob...o-start-54807/

 

Thanks!

 

Well haven't done anything to the car and the engine light cut off by it self. This car has a mind of its own. Lol

 

Professionally speaking you have multiple issues Going on here.
I've done crank sensors on these ss/sc for nearly the exact shut off scenario. If the PCM detects an incorrect number of pulses from the CKP sensor, DTC P0335 sets. So be sure to check/clean all mating surfaces for sensor. if possible check the reluctor wheel for any signs of damage and also check for any build-up on ckp sensor itself.
The other code p0461 is usually due to the lever sender contacts are becoming worn and not returning the proper resistance to the ipc.

 

So basically I need to go ahead and replace the crankshaft sensor since Ive bought a new one already?

 

Wouldn't be a bad idea. Make sure to clean mating surfaces. Plug hole with piece of shop paper towel and clean with scotch pad and then remove towel to ensure nothing gets into engine.
if surface is already bare metal obviously there is no need to clean.

 

Also thought it was weird that stage 2 boosts at max of 18lbs. Stock exhaust as well.
