Help on OBD codes
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.

anyone?
CEL lightg came on again only at start up. Car started but takes longer to crank. Car reumbles into cold start and the RPM meter drips and bounces and feels like it's missing a cylinder and then the |CEL came on. Car runs fine but when stopped..at idle..the car's rpm dips like 50-100 rpm or so every so oftern.

Ok.after hours and hours of scouring the net and reading what's posted here. I have a theory, just no time to check whether it's true or not.
The 2 codes are actually circuit malfunction codes. Circuit malfunction codes seem to only appear if there is no power going to the device or high resistance which leads me to assume it's the wiring harness. The thing is, I have never heard of anyone with a 1997 M104 with a wiring harness problem. From what I hear it was basically isolated to 96>. Any comments welcome.

Thanks bayside, if i find anything else out i'll let ya know.
BTW, the car runs fine after it's warmed up. At a stop light it shakes on and off.
