I just finished up swapping in the cc503 cam along with all of the supporting modifications and other goodies. The car starts and idles fine at 1000rpms and has no driveability issues. To make a long story short, Brian from Pcmforless will be at my neighbors shop next week to tune a modified impala and they are getting my car in for a full tune. I want to make sure its ready this is a rare opportunity!

Ran the codes and this is what it reads in the order it scrolls:

P0300
Mil on
monitrs
5 inc
catalyst
sec air
02 snsr
02 htr
EGR
3 ready
misfire
fuel
comp

The car has never has any SES codes before and ran great before the swap, it still revs and drives fine, I'm stumped here and need some help!

Sorry car is a 1996 z28 M6
cc503
1.6rr
intake
52mm throttlebody
bbk shorty headers
dumped dynomax

 

You only provide one code, the P0300, which is a common random misfire code. Double-check your wires, plugs, boots, and connections. I should point out that this code will not affect performance and Bryan can tune it out.

 

So the only reason the SES light is on is because of the one code(P0300)? It still lists a whole bunch of things after that but only reads one code. I was thinking everything listed was an issue, if it's just the P0300 I guess I have nothing to worry about. The engine runs great throughout the entire RPM band.

 

Word of advise, Dont take advice form ramair95ta. dumbest thing I've ever heard.

 

What the ****?

 

The CPS has been known to be very finicky. Once you add a cam it can detect false mis-fires. Most people tune the sensor out once they get to that point. When the code is set, the PCM does not alter timing in any way.

 

I'm going to bump this again in the hopes that Badazz posts, because I would love to know where I went wrong in my original post.
