Follow-up, Flashing CEL could shortly mean "Change Engine Light" have you car checked out by a reputable mechanic.

Wouldn't it be nice if the car manufacturers provided a light that tells you when it actually was time to change the engine? That would have saved so many people from having major engine failures, don't you think? All those people who suffered IMS failures would have at least had a bit of warning, too.

Nope, the light is a Check Engine light, not a Change Engine light, though we should have Porsche rig something like that up for a future model!

BC.

Been there, done that.

It is your oxygen sensors my friend.

Change them and I'm 99% confident it will fix the problem.

If not, start to look at MAFS and coil packs etc.

Also, and for the benefit of everyone else here, I will share a tidbit of bad advice I received from searching on another forum. Someone suggested unplugging the MAFS to see if this prevented the car throwing up codes, and if so, it is the MAFS which is faulty. BAD IDEA. I unplugged it, car ran just fine but very down on power. When I replaced it with a new MAFS $500 later, the codes came back after 5 minutes. So all I could deduce from that is the car just does not throw up codes if something is unplugged, whether the component works or not.

Good luck!

Well. I guess that would lead me to my next series of questions. How many o2 sensors does the car have? where are they located? Is there anyway to test if there good or not? If I do need to replace them is there any certan type I should get? Thanks for all the help btw y'all have been great!
