2006 Chevrolet Cobalt Q&A

2006 Chevrolet Cobalt Question: Coils help?

Well if my coils are bad, I was told that the pedals would be spongy, it wolud lag in acceleration, and eat gas. Its lacking power out the ass. Does anyone know where the ignition coils are and how to replace them? thanks -
Answer 1
They are attached to the spark plugs, and if the coils are failing, the check engine light will be on and possibly flashing. Is that happening? -
Comment 1
So the coils are attached on top of the plugs, correct? Yeah its on and blinking. -
Comment 2
Have the diagnostic codes checked and diagnose the problem, depending on the engine you can have one coil assembly or 1 coil for each cylinder. This type of misfire may not be a coil, so don't start replacing parts, you will be throwing away your money. These Cobalts also have issues with injectors, there are 4 technical service bulletins regarding misfires! You want to avoid driving your vehicle when the check engine light is flashing, or you will damage the catalytic converter. I would check your emission warranty, this type of problem may still be covered. -
Comment 3
I know that when I took it to get diagnosed, I had the code PO300 (which is a misfire) pop up and an over heating one that isnt causing me problems. Ill check the warranty now. -
Comment 4
Her's some great info about the P0300 code and misfires in general: http://repairpal.com/OBD-Code-P0300 -
Comment 5
I recently purchased an extended warranty from Mogi, silver plan, would that cover it? This is a first for me, I appreciate all the info, Thank you. -
Comment 6
I don't know anything about the plan you purchased, extended warranties are all different so you'll need to look at the fine print. Good Luck! -
Comment 7
Theres no fine print really, I just compared it to the other warranties. I've changed the oxygen sensor myself awhile back, do you hav any info o how to remove and replace the fuel injectors? -
