    engine light switches from blinking to staying on - car cutting back & cuts off when brakes applied or in park, just 1 of numerous car problems

    I only recently took possesion of this car (two days ago from my sister who said she hasn't had any problems) and the first day driving it was completely normal, but the second day as soon as I turned the engine on the "check engine" light began blinking and the car was making a "winding" kind of noise. As I slowed at a stop light the car began to pulsate a bit and as I came to a complete stop the pulsating became more harsh. This happened with every stop. On the highway I had to pretty much put the gas pedal to the floor in order to reach 70mph. I set the cruise control and the car struggled to keep this speed (even driving with no incline). I had an eerily similar issue with a '96 Ford I owned in highschool known as the "blinking light of transmission death" by everyone I talked to about it. *sadness*

    car starts up ok, but engine light blinks on, engine shakes and runs rough, and seems to not have power and wont go up a hill. Also black stuff spits out of exhaust pipe and smells like sulfur. Just filled up with gas 2 days before problem. Also reads 54% oil life.

    Same problem, my power steering started going out a couple of weeks ago, now this. Car won't go, sputters like the engine isn't hitting on all cylinders or something. Replacing the ignition module and coil are our next tries here. The power steering still won't be fixed though! Have read literally HUNDREDS of comments online of people with the same problem. Can't believe GM won't stand behind this. I filed complaints with GM, the FTC and went to the following site: My car only has just over 60,000 miles on it. This is crazy.

I had the same problem. Have it checked at an checkers with one of their computers. I had a multi misfiring. I changed the ignition module on it. It runs great now.

5.3 liter Chevy engine #1 Cylinder not firing at idle

My opinion...

Year? Miles?

There's no way I'd dive into a "HEAD GASKET"
diagnosis without pressure testing the cooling
system and (wet/dry) COMPRESSION testing
the whole engine...

Even if it is a "HEAD GASKET"... the entire engine
might be ready for a REFRESH... and tossing a new
Head gasket into a TIRED ENGINE not insubstantial
(a lot of wasted time & money)...

Come back with some compression numbers...

but don't bother with any of this if your engine oil has water in it.

(in my opinion)

I started my 2006 chevy cobalt this morning and it idles really rough and my check engine light is blinking on and off. It ran fine the other day when i drove it

Rough idle, flashing CEL, low power would indicate a faulty ignition coil. A armchair diagnosis would be to replace the ignition coil. You'll have to swap the the contact stems (rubber conductors between the coils and the spark plugs) and the igniter module.

Simple task requiring a 10 mm socket and ratchet, a 10mm box end wrench, a T-15 torx bit with adapter and a new coil pack. Cost around $100 and takes a half-hour.

2005 chevy cobalt 2.2 is running rough (putting)

Number three cylinder is miss fire,it does not mean it is the coil,although it could be,remove the coil,and boot,and spark plug,inspect them to see if the plug,or boot look bad,replace the spark plug,and if the boot is burned or distorted,replace it,a fuel injector can cause a miss fire also,but change the spark plug and see if this solves the problem,if not replace the coil,if it is a dead miss,then the coil might be bad,as for the water in the fuel ,the cap is missing,,and 5 dollars worth of HEET will not hurt,also,fuel from the fuel station,can have water in it.It happens a lot.

Blinking engine light, rough running, smells like gas from exhaust. Happened all of the sudden.No water in oil. Have to push accelerator to start engine now.Just sounds like it is misfiring.

the blinking light is blinking a code that ID's the cylinder or cylinders that is mis firing, count the blinks, poss causes are defective ignition coil (one for each cylinder) or a defective spark plug, these are the common reasons other problems of course like a dead cylinder from low compression like a bent or burnt valve can also cause this, but that is very unlikely, U don't say engine type so assume this is a gas engine

2005 chevy cobalt check engine light

make sure the gas cap is on tight. vapor recovery system depends on the closure of the gas cap. if that did not solve your problem, I would suggest to get a new gas cap first, before going to the dealer or any repair shop for a turn-up.

2005 chevy cobalt check engine light

You need to get the computer scanned. This can be done at Auto Zone or similar parts stores free of charge. More than likely you will just need new spark plugs and/or plug wires but I cannot be certain without the engine code.
Hope this helps, remember to rate this answer.
