Check engine light and cruise control blinking?

So i just put in a cobb catted downpipe in 3 days ago and today my check engine light came on and my cruise control is blinking also. My car also has spt catback and aps cold air intake and is currently tuned for stage 1. I have been driving my car as easy as you can cause bullwinkle is tuning my car on monday. What is throwing off the engine light and the cruise control, and is it ok to limp it around until i get it tuned? Also, should the lights go away once i get it tuned? Thanks

 

You can go get any auto places to use the OBDscanner to scan/read the engine code to see what's wrong. They can also erase the engine light too. Most places don't charge anything to do that. &your cruise control, I can't help ya there. Sorry.

 

Why not ask your tuner?

 

Ya i PM'd bullwinkle i just wanted to see what everyone else had to say.

 

check eng light is on the cruise light will flash.
most dp cause the check eng light to come on. did the dp come with a spot for the 02 sensor??

 

yes it did

 

Most aftermarket DP's will throw a P0420 code even if you reinstall the rear 02 sensor. Don't worry, it shouldn't affect drivability, your tuner can turn off the CEL.
