Sounds like the problem has been resolved. Clear the codes and see what happens. BTW, you will need to pull the plenum completely off the engine in order to service the rear plugs. I would wait until one of the rear coils fails, and one will, and then take care of the coils and plugs at the same time.

This is strange. The tcs is a traction controll error. If you are getting misfire codes and traction control warnings, then I would have your control module tested to make sure it is not having intermittent power issues to each component.

The trac off light goes on and the engine light is blinking


This is common, when ever the computer sees a fault it will turn the light on and shut down the trac, the trac cant operate correctly when engine is not running good, you will need to have the computer scanned for codes, whenever the engine light comes on the computer stores a code with the problem, a flashing light means it needs attention asap, this mean its misfiring like a bad plug or sparkplug wire, the flashing is because you can cause damage to converter in the exhaust system, many autopart stores will scan the codes for free, for example they may pull a code that says po301 cylinder 1 misfire, this would mean cylinder 1 is misfiring, this take about 5 min, to get the codes, they use a small hand held scanner that plug in inside the car under the dash to the diagnostic connector which comunicates with the computer, hope this is helpful.

The service engine light came on and started to have problems gaining speed and the light started blinking!


This is most likely a misfire. When the light blinks under acceleration it is telling you the engine is in serious need of service, which doesn't necessary mean that the engine is in serious trouble. Have your OBDII port and codes checked. Your local parts store like AUTOZONE will do this for free.

Hi:
Usually the only thing that causes a blinking check engine light is a cylinder misfire. Usually this is caused by a failed ignition module, but to find out specifically,might take some guessing, or a computer download. You can scan the car's computer system, anf find out what codes are tripped. Most auto parts stores, like autozone,will do this for free. If you detect a cylinder misfire code, or similar, that is what you need to get fixed..

Took vehicle for diagnostics & no codes showed up but check engine light stays on. Also the Lok Trac light stays on. This is a 2004 Alero


If the engine light is on there's a code store in your computer, hope they did not charge you, take it to another repair shop, or to Autozone they will do a code reading for free, but don't buy any thing as this is just a selling thing, take the trouble code to a repair shop and see what they say.
