Hiyas,

Thanks ahead for any responses that come out of this thread.

A couple weeks ago, I was at a GTG in Toronto. I started my car and the CEL light came on and it went into limp. Shut the car off tunr it back on, light still on no limp. The car's idle fluctuates when In D and stopped. 500-700. Car sounds a bit louder then usualy, exhuast wise. I pulled the codes and this is what I got...

P0120 - Actuator Actual Valve Pot. Meter
P0203 Injector Cylinder 3 (Y62Y3)

The P0120 I can search and find lotsa info on but i'm still lost on the P0203 one.

If anyone can help with either both or one of these codes, it would be much appreciated.

Thank you,

rocky

BTW, after driving for awhile, the CEL is not on anymore but the car still feels funny and idles a little roght..slightly rough.
