..... and if that isn't the problem (MAF), give the old negative battery terminal disconnect for 5 minutes trick a try. If you have a code reader handy for the OBDII port, see if it will pull any codes for you.

ps: I just changed mine with over 130,000 KM on them on a 2.4L - they were NGK (were all that was avail at the time) and they came out fairly clean looking. Installed AC Delco ones this time.

 

When i first started the car back up i realized i did forget to plug the sensor back in but even after i plugged it back it it still said Service ESC and Service Traction so i dont know

 

Did you try disconnecting the battery (negative post only) for a few minutes?

 

I would re check the MAF sensor, they don't always get plugged back right.

If this is a VVT engine you may have disturbed one or more of the solenoid wires. It's a 2009, so chances are good it's VVT.

 

Have an '08 2.2. Got the AC Delco 41-103 plugs. Do they need to be gapped?

 

They should be pre-gapped. You can check them just to be sure. Now, if one is off, it is not advised to try and adjust it. The tiny center stem part can be broken easily.
If one's not gapped correctly, it's best to return it for a swap out.

 

Thanks

 

I checked the gapping and they were all good and did not try the battery disconnect, it turns out the lights are not coming on anymore so i dont know maybe its a ghost!

 

Not a ghost in the machine, codes will self clear after a number of fault free driving cycles.

Disconnecting the NEGATIVE battery cable as whopper suggested is what we refer to as a "Lobotomy".

If you have a CEL set and you have addressed and corrected to source of the fault, such as not reconnecting the MAF sensor, then you can clear the codes via the Lobotomy route.

But only do so to clear codes that you've addressed, disconnecting the battery just to shut off a CEL is not recommended, as continued driving with certain codes set will ultimately lead to damage requiring more expensive repairs.

 

I would question the plugs that you installed. Were they the recommended AC Delco Iridium plugs that are listed for the vehicle???
