Bought it at Costco for $35.00. You plug into the computer connector under the dashboard and it will give you all the codes for your check engine light being on. I bought my 99 C2 last year and it has always had a little tough time starting but it always will after 1-3 trys. It runs great other than that and very smooth. So here are my codes. If any mechanics can help let me know.

1. Misfire Cylinders Emission Related
2. Misfire Cylinder 4, 3, 2, 6, Emission Related
3. 02 Sensor Circuit Bank 1 Sensor 1
4. 02 Sensor Circuit Bank 2 Sensor 1

I have a pretty good idea here but is this anything bad?

 

I had some misfire codes about a year back and it turned out to be a lose spark plug...

 

How many miles? I would change spark plugs, and check for cracked ignition coils.

 

I believe it was at 62k. My P-Car guy noticed it and tighten them down. I have never had a problem since... or until every thing went nuts yesterday afternoon

 

You can pretty much count on the two rear ignition coils cracking, causing misfires. Looks like your O2 sensors are going as well.

 

Really? I need to drop her off at the shop this week so I will make sure my guy looks at that. I got a bunch of lights yesterday.. Battery/Generator... ABS.. Brake Distribution... My whole interior electronis just turned off... the windows wouldn't go down, AC turned off... everything died but she keep driving... Thank GOD I still have my waarenty...

 

Those symptoms are much different. I'd start with looking at a bad ground in the charging system.

 

Thanks Steve!
