I wanted to thank you for the advise you gave for the P0420 code on a Chevy Cruze. I couldn’t leave anything on it. So I came on here. The 3 computer cables I cleaned the connectors. That way my fix. I have a 2014 Chevy Cruze with 1.4L engine it has 180,000 mile. I have been getting a P0420 code. I would go away and come back. I fixed it just by disconnecting the Negative side on the battery 1st. Now find the computer it’s on the side where the battery is. It’s has 3 connectors on it. I disconnected all 3 connectors and cleaned each side male and female connector with CRC 05103 QD Electronic Cleaner. Let it dry 15 minutes. I plugged all 3 back in. I installed negative battery cable. I started and drove the car 50 miles. It never came back.
Sorry for the late and delayed for when your reply yes it never came back car pass smog with no problems and have not installed any additional parts except oil change I filter

Curious, I just bought this amp, running 2 JL 10w3v3-4 subs, do I need to do big 3 upgrade or will using 4awg for amplifier power and ground be fine?
Cording to JL audio four gauge wire should be just fine I believe that amp has an 80 amp fuse on it for Gauge is good up to 105 A
Hey is your Cruze fix does it still have the p0420 code please reply
